and on. P.13b Before the DM.10 was begun, in December 1944 Lippisch's attention moved to a revised design similar in some respects to the earlier P.11 / Delta VI but keeping the P.13a's sharp sweep angle and solid-fuel ramjet with rotating burner. The wing was essentially that of the P.12/13 but larger at span and cut short at the front for unswept air intakes at the roots. Like the P.11 it had a conventional nose nacelle and cockpit with small twin tail fins either side of a centre section inset on the straight wing trailing edge. The landing skid was moved further back and refined, with a return of the early P.12's small downturned winglets or fins on the wingtips to act as outrigger bumpers when landing. Wind tunnel tests had just begun by the time the Russians arrived in Vienna and Lippisch had to flee.
