Sikorsky FLRAA: The Protest, GAO Ruling, and FARA Fallout

Sikorsky’s protest of the Future Long-Range Assault Aircraft (FLRAA) contract was denied by the Government Accountability Office on April 6, 2023, clearing Bell Textron to move forward with its V-280 Valor tiltrotor design. The GAO found the Army had reasonably rated the Sikorsky-Boeing bid “unacceptable” for lacking required architectural detail, and Sikorsky announced less than two weeks later that it would not take the fight to federal court.¹

Why Sikorsky Lost the Contract

The Army awarded the FLRAA Weapon System Development contract to Bell in late 2022, with an initial value of $1.3 billion to deliver a digital prototype by 2025.² What made the choice controversial was the price. Bell’s evaluated price came in at $8.087 billion. Sikorsky’s was $4.445 billion. That is a gap of roughly $3.6 billion, and the Army picked the more expensive bid.³

The evaluation criteria weighted engineering design and product supportability above cost, and on those factors Sikorsky’s proposal did not clear the bar. Evaluators rated the Sikorsky-Boeing engineering design and development as “unacceptable,” citing four significant weaknesses and 11 additional weaknesses.³ The Army used a plain analogy to describe the problem: Sikorsky-Boeing had provided a drawing showing what the house looked like on the outside but failed to show the functional detail of what the space would look like on the inside.⁴

Specifically, the Army found that Sikorsky did not allocate system functions below the system level, which left evaluators unable to determine how subsystems and components were defined. The Army called this “insufficient evidence and inadequately defined scope” for meeting the government’s Modular Open Systems Approach (MOSA) requirements, and it treated that as unacceptable risk for the development program.³ The solicitation required a rating of at least “acceptable” on each non-cost factor to be eligible for award. Once Sikorsky-Boeing landed at “unacceptable,” the lower price no longer mattered.

What the Protest Argued

Sikorsky filed a formal protest with the GAO challenging the Army’s evaluation on multiple grounds. The company argued the Army had misinterpreted the solicitation’s requirements for architectural detail, and it contended that Bell’s proposal should itself have been found unacceptable.⁵ In effect, Sikorsky was asking the GAO to conclude both that its own bid had been misread and that the winning bid had been graded too generously.

The GAO’s April 2023 Ruling

On April 6, 2023, the GAO denied the protest in a 38-page decision. The office found the Army’s evaluation reasonable and consistent with the solicitation, and it concluded that the Army had reasonably required architectural detail extending down to the subsystem level. Sikorsky, the GAO said, failed to provide that detail.³

The ruling also blocked Sikorsky from pressing the rest of its arguments. Because the Sikorsky-Boeing proposal was rated “unacceptable” and therefore “unawardable,” the GAO held that Sikorsky was not an “interested party” eligible to challenge other aspects of the decision, including its claims about how Bell’s proposal had been graded.³ A company that cannot win the contract has no standing to complain about how the winner was chosen.

Why Sikorsky Didn’t Sue

Sikorsky had one more forum available: the U.S. Court of Federal Claims, where losing protesters can seek judicial review of a denied GAO decision. On April 18, 2023, Sikorsky and Boeing announced they would not pursue that route.¹ Sikorsky said it would shift its focus to its Raider X prototype, which was then competing in the Army’s separate Future Attack Reconnaissance Aircraft (FARA) program.⁶

The Connecticut Political Fallout

The decision hit hard in Connecticut, where Sikorsky is one of the state’s largest employers. The entire Connecticut congressional delegation, five House members and two senators, issued a joint statement after the GAO ruling expressing “deep disappointment” and pledging to “uncover the Army’s process for making this decision and fight to keep jobs here in Connecticut.” The delegation said it had requested a detailed Army briefing on the contract award at least six times since late 2022 and was repeatedly denied while the protest was pending. Senator Richard Blumenthal called himself “deeply disappointed … and infuriated” by both the GAO decision and the Army’s lack of transparency.⁷

Safety questions have also followed the tiltrotor choice. At a May 2024 hearing, Senator Chris Murphy of Connecticut noted that 20 service members had died in four fatal V-22 Osprey crashes between March 2022 and November 2023, and that 60 service members have been lost to the V-22 program overall.⁸ The Senate Appropriations Committee has encouraged the Army to collaborate with the Navy to apply lessons from tiltrotor operations to FLRAA development.⁹

The FARA Cancellation Compounded Sikorsky’s Losses

The consolation prize Sikorsky pointed to after the protest did not last. In February 2024, the Army cancelled the Future Attack Reconnaissance Aircraft program entirely. Sikorsky’s Raider X had been one of two FARA competitors, alongside Bell’s 360 Invictus. The Army cited lessons from Ukraine about the dominance of unmanned systems and the need to redirect billions of dollars toward drone-related investments.¹⁰ Lockheed Martin, Sikorsky’s parent company, said it was “disappointed” and would await a debrief from the Army.¹¹

The Army’s broader “Aviation Investment Rebalance” that accompanied the FARA cancellation redirected funds toward new Black Hawk multi-year procurement, CH-47F Block II Chinook production, unmanned systems, and continued FLRAA development. A subsequent GAO report noted that the restructuring shifted approximately $7.3 billion in planned spending away from FARA and FLRAA to other priorities, driven by concerns about the affordability of developing both programs simultaneously.¹²

Where the FLRAA Program Stands Now

With the protest resolved, Bell’s aircraft, now designated the MV-75, has advanced through several milestones. Bell completed a preliminary design review in April 2024. The Army approved Milestone B on August 2, 2024, formally entering the Engineering and Manufacturing Development phase and exercising the first of nine contract options covering detailed aircraft design and the construction of six prototype aircraft.¹³ Bell has also delivered virtual prototypes that let soldiers assess the weapon system in digital environments.¹⁴

Under the original schedule, the Army planned first flight in 2026, low-rate initial production in 2028, and initial fielding by 2030. In May 2025, Army Secretary Daniel Driscoll and Army Chief of Staff Gen. Randy George tasked Bell with developing a plan to pull the fielding date forward to 2028.¹⁵ The plan is not to speed up design or testing. It is to start building production aircraft alongside the prototypes, exercising an existing low-rate production option in the Bell contract while testing continues. Col. Jeffrey Poquette, the FLRAA program manager, framed it as choosing to “assume a little bit of risk and say, well maybe we can build aircraft during test.” The Army also aims to compress the full-rate production timeline from seven or eight years down to four or five, with an early production decision planned for 2027 ahead of the formal Milestone C.¹⁶

Even so, first flight has slipped. As of April 2026, the Army had not confirmed a date, and the flight had not yet occurred. The Army officially named the aircraft the Cheyenne II at an April 2026 event, but Maj. Gen. Clair Gill, the program acquisition executive for maneuver air, declined to commit to specific milestones, saying “it’s going to happen when it’s going to happen.” Officials pointed to supply chain complexity, roughly 300 tier-one suppliers and nearly 2,000 tier-three and tier-four suppliers, as a primary constraint, along with budgetary uncertainty created by the risk of continuing resolutions or government shutdowns. The Army’s most recent budget request included an increase of nearly $600 million in research and development funds for the MV-75 over the prior fiscal year, which officials suggested could help move the schedule forward.¹⁷

The full program is expected to be large. A 2023 GAO assessment reported the Army’s draft cost position at $74 billion to $76 billion for roughly 600 aircraft.¹⁸ The most recent CRS report, from June 2025, indicates the Army intends to procure up to 334 FLRAA units by the end of fiscal year 2040.⁹ The aircraft is intended to replace roughly 2,000 Black Hawk utility helicopters, though not on a one-for-one basis.¹⁹

What’s Left of the Black Hawk Line

The Black Hawk that Sikorsky builds is not disappearing on the same timeline as the protest loss suggested. Army Chief of Staff Gen. Randy George has said the helicopter will remain in service “a while,” even as FLRAA begins to replace part of the fleet. Army leadership has been reluctant to commit to a new multi-year procurement deal for UH-60Ms beyond the current contract, which runs through 2027, citing changing battlefield conditions and the growing capabilities of drones. A Sikorsky spokesperson said negotiations regarding future Black Hawk procurement are ongoing.¹⁵ Congress supported the purchase of 26 new UH-60Ms in FY2025 as part of the existing multi-year contract.²⁰ Whether Sikorsky wins a follow-on Black Hawk deal is now the open question the FLRAA protest left behind.
