WASHINGTON — Lockheed Martin-owned Sikorsky and Boeing have pitched a tweaked version of the team’s coaxial technology demonstrator — the SB-1 Defiant — which it plans to submit for the U.S. Army’s Future Long-Range Assault (FLRAA) competition, according to the companies.
The modified, competition-ready aircraft design is being called Defiant X, taking the same surname as little brother Raider X, which is Lockheed’s submission for the Army’s other helicopter competition — the Future Attack Reconnaissance Aircraft (FARA) program — running nearly in parallel.
