And with Yangel, then later with Glushko, and a little with Makeev (the projects of silo SLBM as BM).
(Let alone Myasishchev , Lulka, and Lavochkin with rocket planes).
Also the engine skirmish between/among Glushko, Kosberg, Isaev, Lulka, Kuznetsov, with participation of Korolev and partially Chelomei.
Nobody was bored.
That was a real competition, unlike the NASA totalitarism.
