The F-26 Stalma is a single place multi-role fighter being developed by Stavatti Corporation, Tactical Air Warfare Systems Division in St. Paul, Minnesota. The Stalma is a single place, single engine air superiority aircraft offering variable geometry, supercruise, enhanced agility and low observability characteristics. The Short Takeoff Advanced Light Multi-role Aircraft (STALMA) program began in 1989 as a conceptual light weight fighter suitable for the replacement of F-16C and F/A-18C multi-mission aircraft in the late 1990s.

The Stalma evolved as a possible candidate for the USAF Multi-Role Fighter (MRF) program under the Bush Administration. The introduction of the ARPA ASTOVL program in 1993 and the 1995 initiation of the Tri-Service Joint Advanced Strike Technology (JAST) project, resulting in the current Joint Strike Fighter (JSF) program, quelled the necessity for DoD MRF development. Shifting emphasis toward the production of a dedicated international export fighter, Stalma development continues as a commercial venture.
