All efforts were to be spent on perfection and production of the A4 (V-2) as a weapon-in-being. Von Braun managed to continue some development and flight tests of the A9 under the cover name of A4b (i.e. a modification of the A4, and therefore a production-related project).

The Malyutka rocket point interceptor was designed by Polikarpov beginning in 1943. Prototype construction was underway when Polikarpov died on 30 July 1944. His projects were immediately cancelled after his death.
