MOSAIC

The United States Army is searching for a missile cheap enough to be fired in large numbers against the kind of threats that modern battlefields produce by the hundreds, and it wants working hardware ready to demonstrate by the end of fiscal year 2026. A request for information first posted May 15 and updated June 4 with preliminary Industry Day details reveals the Army's Rapid Capabilities and Critical Technologies Office is conducting urgent market research for low-cost interceptors, missiles designed to shoot down drones, cruise missiles, and short-range ballistic missiles, with a hard price ceiling of $1 million per complete round and demonstrations targeted for 4QFY26 on a compressed timeline that gives industry very little margin for delay. The notice, designated MOSAIC-26-03 and issued by the Army Capability Program Executive for Defensive Fires at Redstone Arsenal in Alabama, lays out five distinct problem statements covering every major component of a missile interceptor system: a complete ready-to-fire round, a solid rocket motor, a seeker, a fire control system, and a systems integrator capable of assembling the best available components into a working weapon. The cost thresholds the Army has set are not suggestions. A complete interceptor must come in under $1 million per unit. Individual components, the rocket motor, the seeker, and the fire control system, must each cost no more than $250,000. Those figures represent a fundamental departure from the economics of existing air defense missiles, which routinely cost several million dollars apiece and in some cases tens of millions. The urgency behind this search is not difficult to understand for anyone watching how modern wars are being fought. Russia has launched hundreds of Shahed-series drones against Ukraine in single overnight waves, and Iran has demonstrated the ability to launch large salvos of drones and missiles that can overwhelm air defense systems relying on expensive interceptors. Shooting down those threats with Patriot interceptors, which can cost several million dollars per round, or even shorter-range systems, produces an economically unsustainable exchange rate that adversaries can exploit indefinitely. The Army's explicit goal is to find a supplemental interceptor cheap enough that firing multiple rounds at a single low-cost drone does not represent a financial loss for the United States. The problem statements cover a threat spectrum ranging from air breathing threats, a military term for aircraft and drones that fly under their own power, through cruise missiles, which are essentially jet-powered guided bombs, up to close-range and short-range ballistic missiles, the kind of weapons that follow a curved arc through the atmosphere toward their targets. Covering that full range with a single interceptor family at the stated price points is an engineering challenge of considerable difficulty, which is why the Army has structured the request to accept both complete round solutions and component-level offerings that a systems integrator could assemble into a finished weapon. The complete interceptor, described as an All-Up Round in military procurement terminology meaning a weapon fully assembled and ready to fire, must integrate with the M903 launch station, a wheeled launcher currently used with the Patriot missile system, and must work within the Integrated Battle Command System, the Army's network that links radars, launchers, and command posts into a single air defense architecture. Requiring compatibility with existing infrastructure rather than demanding entirely new ground equipment is a deliberate cost and timeline management decision: a new interceptor that fires from existing launchers and talks to existing battle management networks can be fielded far faster than one requiring new support infrastructure. The seeker, the sensor in a missile's nose that finds and tracks its target in the final seconds of flight, must function in contested and degraded environments, meaning it must continue working when adversaries use electronic warfare to jam GPS signals, blind infrared sensors, or create false radar returns. That requirement acknowledges the operational reality that any future near-peer conflict will involve sophisticated electronic attack from the first moments of engagement, and an interceptor whose seeker can be blinded by jamming is effectively useless in the environment it is most needed. The timeline is compressed to the point of being aggressive by any conventional procurement standard. The Army wants demonstrations of complete interceptors and individual components in the fourth quarter of fiscal year 2026, which runs from July through September 2026. For complete interceptors the Army requires solutions at Technology Readiness Level 6 or higher, meaning a system that has already been demonstrated in a relevant environment, not a concept or a laboratory prototype. For components, the threshold drops to Technology Readiness Level 4, but the demonstration timeline remains the same, leaving participating companies very little runway between the June Industry Day and the required demonstration window. The Army plans to host an Industry Day on June 23, 2026, at the Hyatt Regency Crystal City in Arlington, Virginia, followed by prize competitions for each of the first four problem statements under a statutory authority that allows the government to reward demonstrated performance with cash prizes rather than traditional contracts. The prize competition structure is notable because it allows the Army to evaluate real hardware performance without committing to a procurement contract in advance, and it opens the door to non-traditional defense contractors and startups that might have relevant technology but lack the infrastructure to compete in standard acquisition programs. There will be no prize competition for the fifth problem statement covering systems integration, which the Army intends to handle through a separate acquisition pathway. The systems integrator role described in Problem Statement 5 is itself a significant structural feature of the entire effort. Rather than requiring a single company to design and build every component of a new missile from scratch, the Army is explicitly asking for an integrator capable of combining the best-performing rocket motor, seeker, and fire control system selected through the separate prize competitions into a finished weapon. That approach mirrors the modular open systems philosophy the Department of War has been pushing across multiple programs, and it creates a competitive dynamic where component suppliers have an incentive to make their products interoperable rather than proprietary. The math that drives this entire program is straightforward and sobering. Modern adversaries have demonstrated they can produce far cheaper drones by the thousands, deploy them in mass salvos, and absorb the losses because the economics favor the attacker when defenders are spending vastly more per intercept than attackers are spending per drone. The Army cannot solve that equation by buying more expensive missiles. It can only solve it by making the interceptors cheap enough that the exchange rate no longer favors the other side.
