The AASI Stratocruzer 1250 (sometimes called the 1250-ER) was a proposed turbofan-powered version of the AASI Jetcruzer that never left the drawing board.

Design work had started in September 1991 to provide a business jet with intercontinental range. A military version, the ML-5 intended for surveillance duties, was also planned. Work was abandoned after AASI failed to attract backers for the project in 1995.
