The goal is to create a variant of the SeaSparrow that can be used by the 12 nations in the NATO SeaSparrow Project Office consortium, or NSPO, according to the Navy Sources Sought notice. The deadline is Oct. 19.

The NSPO is looking for a weapon that can be employed against a wide variety of threats. The NSV SeaSparrow “should have capability against current and future threat classes spanning a variety of threat characteristics including velocity (low-speed to high-speed), altitude (sea skimming to high diver), maneuverability (non-maneuvering to high Gravitational (G)-Force maneuvers), and signatures,” the Navy said.

The NSV is also meant to defend the fleet against massed salvos of missiles and function despite jamming.

The weapon “should be able to work in complex natural, contested, Radio Frequency (RF), Electro-Optical (EO), and/or Infrared (IR) environments.”

“The missile should have the capability to discriminate and resolve between multiple closely spaced targets and provide threat-track measurements to support missile guidance, navigation and lethality functions,” the Sources Sought notice continues. “The missile should have the capability to handle threat countermeasures.”

The notice included a graphic that appeared to depict surface ships — including two aircraft carriers — being targeted by a dozen missiles and torpedoes, plus a hostile fixed-wing aircraft and a helicopter. The friendly ships appeared to be using active illumination to paint some threats, while the SeaSparrow used its on-board sensors to intercept others.

NSPO seeks a modular, open-source design that would give the U.S. government “maximum rights in technical data, computer software, and computer software documentation (including source code), design artifacts, and interface specifications.”

“This approach will simplify future upgrades, promote interoperability across consortium platforms, and outpace evolving threats,” the notice said.

The NSPO wants contractors who can provide a complete missile system, including airframe, propulsion, guidance and software. The missile should have no more than a 10-inch diameter and fit inside a Mark 41 vertical launch tube.

The Sources Sought notice emphasized that the missile and its technical data should be releasable to the entire NATO SEASPARROW Consortium: Australia, Belgium, Canada, Denmark, Germany, Greece, the Netherlands, Norway, Portugal, Spain, Turkey and the U.S. Other users include Thailand and the United Arab Emirates.

The Block II RIM-162 Evolved SeaSparrow is currently manufactured by Raytheon, which doubled production to more than 350 missiles in 2025. Amid naval operations in the Persian Gulf, where Iran has launched numerous missiles and drones against dwindling stocks of U.S. and allied interceptors, future demand for short-range air defense weapons is likely to be brisk.

First fielded in 2004, the Evolved SeaSparrow is descended from the 1950s AIM-7 Sparrow radar-guided air-to-air missile.

Though the original Sparrow had a mixed combat record as an aerial combat weapon in the Vietnam War, the Evolved SeaSparrow was intended as a low-cost defense against anti-ship missiles, aircraft, helicopters and fast attack boats. The current version has an estimated range of around 30 miles.

The service sent out a request this week for manufacturing 133,014 Guided Multiple Launch Rocket System, or GMLRS, rockets by 2034, according to the Army’s Sources Sought notice. Contractors have until Sept. 1 to submit white papers on plans to meet that quota.

The timeline calls for churning out 19,002 rockets per year from 2028 to 2034, with the first actual deliveries starting in February 2030.

“The scope of the contract includes production, tooling, engineering change proposals, and supporting activities of GMLRS rockets including unitary, alternative warhead (AW), and extended range (ER) rockets,” the notice said.

Current GMLRS manufacturer Lockheed Martin already announced last year that it is ramping up production capacity to 14,000 rockets annually. The Army’s new plan would require a nearly 36% increase in capacity on top of that.

“Submissions must outline the most efficient and cost-effective methods for achieving this production rate,” the Army noted. Army efforts to ramp up U.S. munitions production have stumbled, including a facility to manufacture components for 155mm shells that failed to produce any parts.

GMLRS rockets are launched from the M270 Multiple Launch Rocket System armored vehicle. The munitions can also be fired from the smaller truck-mounted M142 High Mobility Artillery Rocket System, or HIMARS.

The base version of GMLRS has a range of 70 kilometers, while the extended-range version can reach up to 150 kilometers.

Lockheed Martin had delivered 75,000 GMLRS rockets to the U.S. Army by 2024. But that still hasn’t satisfied demand for the munitions.

Originally designed as Cold War weapons to unleash massive firepower against a hypothetical Soviet attack on Europe, U.S. multiple rocket launchers became some of the stars of the war in Ukraine.

The M270, HIMARS and their GMLRS rockets have proved instrumental in enabling Ukrainian resistance to the Russian invasion. GMLRS rockets devastated targets such as command posts, supply depots and troop formations.

Ukraine even used HIMARS to hit a power plant inside Russia last September. However, heavy Russian jamming of the GPS guidance system in the rockets eventually compromised some effectiveness.

Between deliveries to Ukraine and a protracted conflict with Iran, U.S stockpiles of GMLRS and other guided munitions have been depleted. Replenishment, meanwhile, has been complicated by a shortage of rocket motors.

The goal is to create a family of drones that can “represent the full range of airborne threats, spanning from inexpensive ‘hobby drones’ to the most advanced adversary fighter and large-scale aircraft,” according to the Air Force’s Request for Information, which has a deadline of Sept. 28.

At the same time, the Air Force desires next-generation target drones that are so inexpensive and easy to manufacture that they can be “treated as attritable or expendable when required.”

As with drones and other new technologies, the Pentagon is turning to private industry for fresh ideas, “including commercial, modified commercial, dual-use, and non-developmental solutions,” the RFI said. “The government is particularly interested in non-traditional, commercially derived, or dual-use solutions that offer advantages in cost, scalability, and simplicity over legacy systems.”

The new target drones are expected to simulate a wide array of capabilities.

For fighters, the drones should have “supersonic capabilities (up to and exceeding Mach 1.6 at 40,000 feet), high-agility/high-G combat maneuvers, precise low-observable Radar Cross-section (RCS) profiles, multi-spectral Infrared (IR) signatures, active RF emissions, and integrated Electronic Attack (EA) capabilities,” according to the RFI.

To simulate C-130-sized multiengine aircraft, the focus is less on high performance and more on “matching the physical scale, slow subsonic flight envelopes, and propeller or turbofan propulsion characteristics of larger multi-engine aircraft. These platforms must prioritize representative physical volume, basic RF/IR emissions, and realistic radar returns to verify missile seeker guidance, and warhead lethality against large-frame targets.”

For even bigger aircraft, such as strategic bombers and AWACS planes, the key is “replicating the massive physical dimensions, multi-spectral thermal signatures, and heavy-aircraft radar strategic threats.”

To mimic big Group 5 unmanned aerial vehicles, the target drone should be capable of flying at 50,000 feet. For Group 3 and 4 UAVs, the targets should be capable of flying at Mach 0.5 to 0.8, and maneuver at 3 to 6 Gs. For small Group 1 and 2 drones, the targets should fly at speeds of less than 150 knots and be capable of drone-swarm operations.

Remote-controlled target drones have been used for nearly a century, including Britain’s Queen Bee — a converted Tiger Moth trainer — in the 1930s.

More recently, the U.S. Air Force has relied since 2007 on the subsonic — and subscale – BQM-167A. At 20 feet long and with a wingspan of 11 feet, it hardly resembles a 67-foot-long Chinese J-20 stealth fighter or a 108-foot-wide Chinese H6 bomber.

The Air Force also has the QF-16, a converted F-16 that can play the role of a full-sized target, such as a fourth-generation fighter. While a practical way to make use of retired jets, they aren’t meant to simulate fifth-generation stealth fighters or large aircraft, nor are they cheap enough to be expended in quantity.

Consequently, DARPA wants a hypersonic scramjet cruise missile that is capable of evading enemy interceptors.

“Future U.S. military operations face increasingly significant challenges from the rapid proliferation and advancement of highly capable Integrated Air Defense Systems (IADS) by peer adversaries,” warned DARPA’s Request for Information, which is due October 6. “These systems threaten to restrict the operational freedom of U.S. forces and diminish the effectiveness of current stand-off strike capabilities.”

The Next Generation Hypersonic Cruise Missile, or NGHCM, aims to demonstrate that it is possible to develop a cruise missile that is both survivable and affordable enough to be manufactured in large quantities.

“This demonstrator must establish the foundation for a next-generation capability that delivers a revolutionary leap in operational performance—specifically in range, cruise speed, and/or altitude,” DARPA said. “DARPA strongly encourages responses to this RFI from non-traditional defense contractors and emerging technology developers.”

The RFI asks companies to address three “focus areas.” The first is the overall missile concept.

“How does the architecture balance advancements in foundational physical parameters (payload, range, speed, altitude) against other critical factors (e.g., midcourse maneuverability, signature, or platform capacity) to achieve a revolutionary leap in mission effectiveness and survivability?” the RFI asks.

The missile’s launch platform is another consideration. Potential options listed in the RFI include tactical fighters, external or internal mounts on heavy bombers, surface-based vertical launch systems, and “Heavy Ground-Launch / Strategic Defense Class” platforms that would “maximize the range/payload advantages of an airbreathing cruiser paradigm at larger scales.”

DARPA is also looking for a weapon that could be quickly fielded. Companies are asked to “identify an optimized, accelerated schedule to reach first flight for the major technical milestones and review gates, rather than relying on traditional, sluggish acquisition models.”

The second focus area involves demonstrating technologies such as “air-breathing propulsion systems, high energy density fuels, advanced booster technologies, high-temperature materials, thermal management solutions, and high-performance power generation/ actuation/fuel systems.”

The third focus area seeks innovative ways to test the missile quickly. While the RFI doesn’t specify technical parameters, it does note that testing should address “the ability to scale to different missions and distances from 250 nautical miles – 2000 nautical miles.”

The RFI does not specify a speed requirement, although hypersonic is defined as an object traveling faster than Mach 5.

DARPA also wants a hypersonic missile that can be tested without drawing too much attention.

“These concepts should advance the state-of-the-art for collecting critical flight test data allowing for rapid deployment and execution while providing fewer observable indicators of imminent testing,” the RFI said.

Russia has already fielded a hypersonic scramjet cruise missile in the form of the 3M22 Zircon.

Russia has launched Zircons at Ukraine, and Ukraine claims to have downed some of them with U.S.-made Patriot interceptors.

The goal is to “integrate a 50mm ammunition solution to effectively track, engage, and defeat Class 1, 2, and 3 UAS threats,” according to the Army’s Sources Sought notice. The deadline is Aug. 31.

While the notice from the Army’s Project Manager, Maneuver Ammunition Systems office does not provide any technical specifications, it signals the Army’s interest in a rapid-fire cannon for counter-UAS, or C-UAS, defense.

In particular, the Army will conduct a live-fire demonstration using Northrop Grumman’s XM913 Bushmaster 50mm chain gun, with companies supplying 50mm ammunition for testing.

Contractors are asked to provide “a detailed description of the company’s capabilities pertaining to C-UAS, proposed C-UAS system architecture, fire control/sensor integration, detailed draft test or demonstration plan, and how the platform will successfully employ the 50x228mm ammunition against the specified target set. In addition, the response shall provide a detailed, estimated timeline and schedule to design, integrate, and deliver a weapon system ready for a live-fire demonstration.”

The cannon is intended to destroy a broad range of drones, from Group 1 to Group 3. This includes tiny quadcopters all the way to medium-sized UAVs weighing up to 1,320 pounds and traveling at 250 knots.

Such drones have emerged as perhaps the biggest threat to armored vehicles, which have been largely driven off the front lines of the Ukraine war because of masses of UAVs.

The XM913 is slated to be the primary weapon on the XM30 Mechanized Infantry Combat Vehicle, which is intended to replace the M2 Bradley. In 2023, the Army awarded contracts to American Rheinmetall and General Dynamics Land Systems to develop prototypes for the XM30, formerly known as the Optionally Manned Fighting Vehicle.

The XM913 weighs 692 pounds and can fire single shots, bursts, or up to 200 rounds per minute. It will fire the XM1203 Armor Piercing Fin Stabilized Discarding Sabot with Trace, or APFSDS-T. More significant for targeting agile and fast drones, the XM913 will use the XM1204 High Explosive Airburst with Trace, or HEAB-T.

HEAB-T “will most likely be the standard ammunition, replacing the High Explosive (HE) ammunition in service today that relies solely on a point detonating fuze capability,” claimed a 2020 Army news release.

HEAB-T will use a programmable fuze with point detonate, point detonate delay and airburst modes.

“Today, a gunner uses high explosive rounds fired from the 25mm M242, and has to walk rounds into each target to achieve the desired effects,” the news release said. “With the HEAB-T, the gunner can depart from this type of engagement. By using airburst mode, the round will be programmed with range to the target — and other important factors — for maximum lethal effect with an order of magnitude fewer shots.”

While “flak” was once thought obsolete because of surface-to-air missiles, armies are turning to cannons and machine guns as cheaper alternatives to using $4 million missiles — or wearing out manned fighter jets — to destroy a $20,000 drone.

Ukraine has had some success in creating dense belts of short-range anti-aircraft cannons and mobile machine guns to stop Russian drones.

SensorMAX, developed by Lockheed Martin, uses AI and machine learning to analyze acoustic sensor data, update the sensor model — and then immediately transmit the updates over the air to anti-submarine warfare, or ASW, platforms.

During RIMPAC maneuvers near Hawaii, Navy MH-60R helicopters dropped sonobuoys, which fed data to SensorMAX. It in turn assisted the crews with target identification.

“Ground operators retrained SensorMAX’s models on new sounds in minutes, then transmitted AI-enhanced undersea intelligence OTA [over the air] using an encrypted data link directly back to the helicopter and the fleet,” according to a Lockheed Martin news release.

Lockheed described the system as the “Navy’s AI portable sonar expert.”

“Taking in subsurface acoustic data from a network of sensors, SensorMAX provides a continuous data stream to the aircrew and sends information to the ground station,” the company continued. “When a new target is identified, system operators label the identified noise signature, retrain the model on the new data and push a small update packet back to the aircrew.”

The system allows aircrews to manage up to eight simultaneous sonobuoy surveillance feeds, “doubling the capacity of legacy capabilities,” Lockheed said.

The company estimated that each retraining cycle for the model takes under five minutes.

SensorMAX integrates data from a variety of sensors, which makes it useful for air and ground operations as well as naval, according to Lockheed Martin.

“Lockheed Martin’s collaboration with FUSE Inc. enables secure, resilient software delivery to deployed aircraft, allowing SensorMAX’s trained AI models and mission software to be updated rapidly without interrupting operations,” the company said.

“By demonstrating platform-agnostic AI intelligence and classification, the future fleet can leverage any acoustic sensor to expand the protective ring around high-value assets and accelerating the ASW kill chain,” Lockheed Martin continued.

China is also integrating AI into ASW. Chinese media claimed last year that researchers had developed AI which evaluates data from multiple sources, including sonobuoys as well as data on water temperature and salinity.

The Next Generation C-sUAS Missile project comes as the U.S. and other nations are pursuing lasers, microwaves and other alternatives to kinetic anti-drone weapons, such as missiles and cannon, which are seen as too expensive and in short supply.

The Army wants to quickly develop an “extended-range, quick-response missile to defeat Group 2 and Group 3 small Unmanned Aircraft System (sUAS) threats,” according to the Army’s Sources Sought notice. The deadline is August 20.

The initial specifications are for a missile that can intercept a drone flying at 6 kilometers altitude, at a range of more than 16 kilometers. The ultimate goal is to destroy drones flying 8 kilometers high, at a range of more than 25 kilometers. Missile guidance would be via a radar seeker.

NGCM appears intended as a step up — but still compatible — with the Army’s Coyote C-UAS missile system.

“The Army is looking for NGCM to be produced and integrated into the existing Coyote Launch System to provide extended range, rapid launch time, and reduced time-to-target over current effectors,” the notice said.

The weapon is intended to stop Group 2 and 3 drones. Group 2 drones have a maximum gross takeoff weight of 21 to 55 pounds, fly below 3,500 feet and have a speed of less than 250 knots, according to the Department of Defense’s UAV classification system. This includes models such as Boeing’s ScanEagle. Group 3 drones, such as Insitu’s RQ-21 Blackjack, have a takeoff weight under 1,320 pounds and fly below 18,000 feet at a speed of less than 250 knots.

The NGCM missile should take less than five seconds to leave the launcher after the operator gives the fire command.

“The missile must be compatible with the Coyote Launcher with minimal to no modifications,” the notice said.

In addition, the missile must also fit with existing air defense systems, including the Sentinel A3/A4, LTAMDS and TPQ-53 radars.

The Army envisions the NGCM missile system in two versions. The fixed-site version would be equipped with a variety of sensors. A mobile version would be “mounted on tactical vehicles for employment at the halt and on-the-move, providing a scalable capability at the tactical edge.”

The Army is aiming for Technology Readiness Level 7 — prototype testing in the field — by the end of fiscal 2027. Contractors will need to have 50 missiles ready for operational assessment by the beginning of 2028.

Significantly, the Army desires missiles costing less than $150,000 apiece as part of a bulk purchase of 5,000 missiles. While that’s a bargain compared to a $4 million Patriot air-defense missile, critics may still question the economics: An Iranian Shahed-136 drone costs around $35,000.

That’s one reason for the drive to develop anti-drone lasers that, theoretically, cost only pennies per shot. On the other hand, missiles can function in bad weather that disrupts laser beams.

“The current industrial base has demonstrated significant challenges, including production delays, quality control issues, and critical obsolescence (i.e., diminishing manufacturing sources and material shortages) across key engine components,” warned the Air Force’s Request for Information. The deadline is Aug. 28.

“The government will pursue a strategic competition requiring industry to innovate manufacturing and guarantee supply chain resiliency,” the RFI said.

The initiative comes as the Air Force struggles with its jet engines.

For example, F-35 fighter deliveries and upgrades have been delayed by engine issues, with a Government Accountability Office report noting last year that “the engine contractor is still not delivering engines to contract specifications after 20 years of production.”

Meanwhile, B-52 modernization has been stalled in part by engine issues that have raised costs by $3 billion and delayed initial operational capability by 15 months, according to GAO.

In turn, the Air Force is now embarking on a multiyear fighter engine procurement project that envisions more than 180 engines per year by 2034. The RFI specifically cites engines for the F-15EX and F-16.

The RFI promises “five foundational pillars designed to drive a paradigm shift in engine procurement and sustainment,” as the government shifts from “legacy procurement toward incentivizing industry-led technological evolution and capacity expansion.” These include “holding vendors accountable” for delivering new engines that are more capable, reliable and cheaper.

The Air Force will focus “on the total lifecycle cost of the engine, not just the initial purchase price.”

Contractors are also responsible for ensuring reliable supply chains.

“We will implement an acquisition strategy that prioritizes ease of maintenance and establishes a resilient, sustainable supply chain from day one,” the Air Force said. “This effort is designed to solve key fleet-level issues by requiring a newer engine with improved supportability.”

“The result is a streamlined logistics footprint that reduces downtime, lowers the burden on our maintainers, and ensures the continuous flow of parts and support to maximize flightline readiness.”

Ultimately, the question is whether the U.S. defense industrial base can deliver. The Air Force intends to “enforce stringent producibility requirements.”

“We will select a partner capable of scaling production to meet surge requirements, guaranteeing a steady and uninterrupted supply of engines for USAF/FMS [Foreign Military Sales] aircraft (e.g. F-15EX and F-16) programs,” the RFI reads.

Companies responding to the RFI are asked to provide a variety of details, such as a timeline for developing and manufacturing an engine. They should also specify “at what minimum volume your supply chain can justify private capital investments (such as facility expansion, tooling modernization, or advanced automation) and how those investments will structurally lower your long-term unit costs.”

With nations competing to obtain raw materials — and China restricting sales of rare earths — the Air Force wants to be certain manufacturers can find the raw materials they need.

“From your company’s market perspective, what are the primary raw material constraints (e.g., specialized titanium/nickel alloys) or manufacturing process bottlenecks (e.g., advanced casting or forging capacity) that pose the highest risk to scaling up fighter engine production?” the RFI asks.

Ukrainian F-16s have destroyed more than 2,500 Geran and Gerbera one-way attack drones, wrote airpower expert Justin Bronk in an analysis of the Ukraine air war for the Royal United Services Institute, a British think tank.

“[The] use of fighters against such drones has consumed an unsustainable number of airframe flying hours and air-to-air missiles … since mid-2024, when the Ukrainian Air Force received its first Western aircraft and trained crews,” the analysis reads.

“Russian industry produces more than 6,000 [one-way attack] drones per month, and fighter aircraft have only a finite number of airframe hours available before they need time consuming deep maintenance cycles to be performed at a factory by expert technicians.”

Ukraine’s fleet currently operates an estimated 39 F-16s, out of about 79 promised by various Western European nations. Ukraine also flies an estimated four Mirage 2000-5 fighters, out of up to 20 promised by France, plus a few Soviet-era Su-27 and MiG-29 fighters.

The F-16s have been a game changer in the Ukraine air war. They enable Ukraine’s small air force to launch stand-off attacks against ground targets using American-made JDAM and French-made AASM Hammer glide bombs. The threat they pose to Russia’s air force became evident earlier this month, when a Ukrainian F-16 reportedly downed an Su-35 over eastern Ukraine.

Ironically, the F-16 has proven such a capable aircraft that it has become a victim of its own success.

“The F-16 fleet has been over-tasked, mostly by C-UAS [counter-drone] interception duties, for which there is almost unlimited demand over time,” Bronk told Defense News.

The root of the dilemmas is that Ukraine is squeezed between multiple aerial threats.

In addition to drone strikes, Russia has launched numerous cruise and ballistic missiles at Ukrainian cities. Russia has become adept at launching massive combined strikes that begin with waves of drones, followed by cruise missiles, such as the Kh-101, and then ballistic missiles, such as the Iskander-M and Kinzhal.

Ukraine has managed to at least partially tame the drone threat by creating dense belts of short-range air defenses, or SHORAD. These SHORAD belts combine short-range anti-aircraft missiles, anti-aircraft guns, mobile machine gun teams and a variety of homegrown interceptor-drones.

The drawback there is maintaining dense SHORAD coverage along the 745-mile front line — plus defending cities in the rear — with short-range weapons.

“What unites all these mobile air defense teams and counter-drone teams is that their equipment and ammunition is relatively cheap and thus their operations are sustainable,” the RUSI analysis noted. “However, they are relatively personnel intensive to deploy at scale and require both force density and geographical depth to be effective.”

These limitations also point to the difficulties NATO would face in creating its own Ukrainian-style SHORAD system.

“NATO cannot replicate the density of SHORAD defenses that Ukraine deploys for C-UAS coverage, due to the huge personnel requirements of doing so on a sustainable basis,” Bronk told Defense News.

However, NATO could invest in radar-guided anti-aircraft guns to protect key installations, such as airbases and headquarters, and develop cheaper drone-killing munitions for aircraft such as the APKWS II rocket.

Nonetheless, this still leaves Russia’s cruise and ballistic missiles, against which SHORAD is largely ineffective.

As with the U.S. and Israel versus Iran’s missiles, Ukraine must carefully manage limited stockpiles of air defense interceptors like the American-made Patriot and the European-made SAMP/T.

Ideally, Ukraine should rely on SHORAD to stop the drones, while reserving its F-16s for other missions, Bronk argues.

“Other systems need to be used wherever possible for [one-way attack] drones so that F-16 capacity can be used to intercept cruise missiles and deliver strike missions,” Bronk explained. “Within the Ukrainian Air Force inventory, it is by far the most efficient asset for this.”

Bronk believes that F-16 stand-off ground attacks could be even more effective — if Ukraine’s high command was less rigid.

“There is potential for the Ukrainian Air Force to have greater effects if squadrons and wings are given more authority to plan strikes themselves rather than being centrally tasked by Army-centric headquarters elements,” he said.

The Defense Department has put out a solicitation for robot boats that are capable of launching small attack drones — with technology mature enough to be deployed to the field within 120 days.

The goal for the Suitable Warfighting Adaptive Payloads, or SWAP-USV, project is to find “mature, market-ready [unmanned surface vessels] fully integrated with two or more mature, market-ready aerial drones to detect, identify, track, and defeat hostile threats,” according to the Defense Innovation Unit solicitation. The call out set a response deadline of Aug. 10.

To make this happen, DIU created a year-long contest backed by $100 million in prize money. DIU wants to “partner with established maritime manufacturers, autonomy developers, sensor manufacturers, and UAS developers to execute a multi-phase Prize Challenge.”

The SWAP-USV project is billed as a solution to a problem that has also plagued missile and drone defense on land: the economics favor the offense.

“The cost-exchange ratio for detecting and neutralizing asymmetric maritime threats in contested environments is heavily skewed in favor of the adversary,” the DIU solicitation states. Nor can the U.S. military continue to rely “on exquisite, multi-million-dollar naval and aviation assets to intercept these inexpensive targets.”

The solicitation paints the picture of a drone boat that can carry, launch and control at least two small UAVs. The UAVs together should be capable of conducting kinetic strikes with a combined payload of at least 2 kilograms, or just over 4 pounds.

DIU wants a mix of recoverable and one-way attack drones that can patrol ocean, coastal and riverine waters, and loiter on station. The drones, according to the solicitation, should “support one or more operational effects, including ISR, comms relay, electronic warfare, payload delivery, or precision engagement of moving or stationary, as applicable, under operator command.”

The Pentagon also wants the system to be mobile enough to fit into a standard cargo container, on road trailers or on C-17 and C-130 transports.

“Solutions that can launch from unimproved locations or provide additional launch flexibility, i.e. remotely from a container, will be looked upon favorably,” DIU noted, adding that the UAVs should be “technically mature and have an established production line.”

Interestingly, among the maritime threats the DIU solicitation cites are “‘go-fast’ smuggling boats, and semi-submersibles.” Drug cartels have used semi-submersibles to transport contraband from South America to the U.S., and such pseudo-submarines are hard to detect.

The SWAP-USV project calls for robot craft capable of “autonomous surveillance and interdiction of defined maritime operating areas, maximizing operational coverage, probability of detection, interdiction effectiveness, and time on station while minimizing daily operating cost, logistics burden, and required personnel.”

The surveillance elements of the solicitation state that the drone boat must be able to “autonomously follow or shadow a vessel of interest, and autonomously intercept a noncooperative, maneuvering vessel. Autonomous execution of these functions is desired but not required.”

The SWAP-USV Challenge, meanwhile, comprises three “sprints,” or phases, each with separate prize money. To sweeten the pot further, companies that pass the test in each phase will be eligible for procurement contracts backed by a $200 million budget.

Sprint 1 calls for in-water testing in fall 2026, with a goal of deploying a system in the field within 120 days.

“Solutions must include a complete mission ready USV with integrated drone capability system available for testing and evaluation within 29 days of down-selection for Sprint 1,” the solicitation specified. There will be $40 million in prize money.

Sprint 2 will have a fall 2026 deadline and in-water testing in early 2027, with the focus on “expanded payloads, upgraded autonomy, and multi-vendor integrations.” The prize money for that timeframe will also be $40 million.

Sprint 3 will take submissions in early 2027, with in-water testing in summer 2027. The goals of this phase will be announced later, but there will be $20 million in prizes.

Companies must specify which phase they want to join. “The government reserves the right to assign applicants to [Sprint] cohorts based on technical and manufacturing maturity,” the solicitation noted.
