VERIFICATION
Sikorsky’s X2 Still Needs a Customer After FARA and FLRAA
Verified as of September 27, 2026
Modern Warfighter reviewed the government records and attributed reporting behind each consequential claim in this analysis. A Confirmed claim is stated in the cited primary record. A Qualified claim is supported, with its limitation noted beside it.
Verified Claims
Sikorsky-reported performance
Qualified. X2’s 250-knot flight in 2010 and the S-97 objective of hovering at 10,000 feet on a 95-degree day are Sikorsky figures. The analysis labels its speed figures as company-reported.
Records: Sikorsky, October 2010 release and Sikorsky, X2 final flight release, July 2011
S-97 accident cause
Confirmed. NTSB determined that the probable cause of the August 2, 2017, S-97 accident was a design change in the fly-by-wire control system that increased cyclic stick sensitivity during the transition from ground to flight mode. The change magnified the pilot’s inputs and led to over-control in roll and contact between the upper and lower rotors.
Record: NTSB final report, ERA17LA263
About three and a half seconds
Confirmed. NTSB’s specialist timeline records transition mode beginning at 55.7 seconds and blade contact at 59.2 seconds, an interval of 3.5 seconds. The same report gives the S-97 rotor diameter as 34 feet.
Record: NTSB Helicopter Specialist’s Factual Report, ERA17LA263
Defiant blade delay
Qualified. Dan Bailey, the Army’s Joint Multi-Role program manager, told Defense News in September 2017 that manufacturing Defiant’s rotor blades was the challenge behind its first-flight delay. This is an Army official’s statement as reported by Defense News.
Record: Defense News, September 11, 2017
FLRAA protest decision
Confirmed. GAO denied Sikorsky’s protest of the FLRAA award to Bell on April 6, 2023. It found the Army reasonably rated Sikorsky’s proposal unacceptable under the architecture subfactor because the proposal lacked the architectural detail the solicitation required. That rating made Sikorsky ineligible for award.
Record: U.S. Government Accountability Office, B-421359, B-421359.2
FARA design attributes
Confirmed. Key FARA design attributes included a maximum gross weight of 14,000 pounds, a 40-foot rotor diameter and a speed of 180 knots.
FARA cancellation
Confirmed. The Army announced on February 8, 2024, that it would end FARA development at the conclusion of fiscal 2024 prototyping activities.
Record: U.S. Army, February 8, 2024
Raider X unflown at cancellation
Qualified. Neither FARA prototype had flown when the Army announced the cancellation. Coverage that day reported that first flights of both were still planned for later in the fiscal year. The claim rests on contemporary reporting and Sikorsky’s own statements. No government record of flight status was reviewed.
Record: DefenseScoop, February 8, 2024
Rebalance rationale
Confirmed. Army budget officials told GAO that affordability was the primary reason for the restructuring. Buying FARA and FLRAA simultaneously would have consumed nearly the entire Army aviation budget. Army leadership determined that FARA offered only marginally better reconnaissance and surveillance capability than other capabilities in development, at much higher cost.
Record: U.S. Government Accountability Office, GAO-26-108025, p. 4
$7.3 billion reallocation
Confirmed. Army officials told GAO the restructuring shifted about $7.3 billion across fiscal 2025 to 2029 plans. That total included $4.4 billion from ending FARA development, $2.2 billion from delaying the improved turbine engine and about $690 million from canceling the UH-60V upgrade.
Record: U.S. Government Accountability Office, GAO-26-108025, pp. 4–5
Capability effects
Confirmed. GAO found that ending FARA reduced the Army’s planned crewed reconnaissance and attack capability and delayed air-launched effects. The Army revised launched effects to prioritize ground launch, with future air-launch work focused on Black Hawk and potentially other aircraft.
Record: U.S. Government Accountability Office, GAO-26-108025, pp. 6–7
NGRC concept-study award
Qualified. NSPA awarded Sikorsky one of three parallel NGRC concept-study contracts in July 2024 to examine integrated platform concepts. Sikorsky’s announcement tied its concept to X2 and its European industry group. The record is Lockheed Martin’s announcement, which quotes NSPA’s general manager. NSPA’s own release was not reviewed.
Record: Lockheed Martin, July 26, 2024
Korea CH-53K withdrawal
Qualified. Sikorsky told Janes on October 24, 2025, that the budget for Korea’s Special Operations Heavy Helicopter program did not align with the investment required to field CH-53K, and it withdrew from the competition. This is a company statement as reported by Janes. The 2024 link between the X2 technology-transfer offer and CH-53K rests on Aviation Week reporting.
Record: Janes, October 2025
Korea X2 proposal
Qualified. Korea’s Financial News reported that Sikorsky proposed joint development of an X2-based High Speed Medium Utility Helicopter on September 9, 2026, its second public proposal after one in July. This rests on press reporting of a company presentation.
Bell and KAI memorandum
Confirmed. Bell announced on April 28, 2026, that it had signed a memorandum of understanding with Korea Aerospace Industries to explore MV-75-based solutions for Korea’s High Speed Medium Utility Helicopter program.
Record: Bell, April 28, 2026
NGRC concept-design phase
Qualified. NSPA launched the NGRC concept-design request for proposals on July 31, 2026, with six participating nations. It invites four pre-qualified bidders to propose up to two concept designs each. Bids are expected in August 2027, and NSPA plans to finish its evaluation by the end of 2027. The record is NSPA’s release as republished by HeliOps. NSPA’s own page was not reviewed.
NGRC bidders and Boeing
Qualified. Aviation Week reported that Airbus, Boeing, Leonardo and Sikorsky passed NGRC pre-qualification. European Security & Defence later reported that Boeing opted out of direct participation to focus on existing aircraft such as Chinook. No Boeing or NSPA statement confirming the withdrawal was found.
Records: Aviation Week, July 2026 and European Security & Defence, August 2026
NGRC attributes
Qualified. NSPA’s published attributes call for an unrefueled range above 900 nautical miles and a radius of action above 400 nautical miles with 30 minutes of loiter. Cruise speed is optimally 220 knots or more and not less than 180. Shipboard aircraft must fit an NH90 NFH or AW101 footprint, with optional rotor and tail folding. The NSPA document reviewed dates from 2021. The troop capacity was checked against published reporting, as were the availability and payload targets.
Records: NSPA, NGRC Industry Day document, Vertical, October 2023 and European Security & Defence, February 2025
Sikorsky’s NGRC proposal
Qualified. Aviation Week reported Sikorsky’s July 16, 2026, announcement that it would develop and produce its NGRC aircraft in Europe. It also reported that Sikorsky’s concept work paired a conventional single-rotor design with an X2 compound. These are company statements as reported. Supplier names in the analysis were not independently checked.
Record: Aviation Week, July 2026
NGRC schedule
Qualified. European Security & Defence reported an NGRC timeline with flight trials from 2032 and deliveries from 2035. NSPA’s release gives dates only through the 2027 evaluation.
