A series of tailless research gliders built by General Aircraft Ltd, having differing plan forms with various degrees of sweepback. Designed from 1943 to 1947 three were built under the designation of G.A.L. 56 having a common fuselage nacelle built from steel tubing covered with wooden formers and plywood.
The wings were of wooden construction covered with sheets of low-grade wood interspread with processed paper. On flight trials the gliders were towed by a Spitfire Mk.9.
Flight tests commenced in mid-November 1944.
The GAL.56/02 Medium U was as the GAL.56/01 but with small parallel centre section.
The GAL.56/03 Maximum V was as the GAL.56/01 but with 36.40 degrees sweepback.
The fourth glider in the series was built as the GAL.61.
