After the Revolution was crushed in Budapest, the Soviets took away most of the Hungarian People's Army's equipment, including dismantling the entire Hungarian Air Force, because a sizable percentage of the Army fought alongside the Hungarian revolutionaries. Three years later in 1959, the Soviets began helping rebuild the Hungarian People's Army and resupplying them with new arms and equipment as well as rebuilding the Hungarian Air Force. Satisfied that Hungary was stable and firmly committed once again to the Warsaw Pact, the Soviets offered the Hungarians a choice of withdrawal for all Soviet troops in the country. The new Hungarian leader, János Kádár, asked for all the 200,000 Soviet troops to stay, because it allowed the socialist Hungarian People's Republic to neglect its own draft-based armed forces, quickly leading to deterioration of the military. Large sums of money were saved that way and spent on feel-good socialist measures for the population, thus Hungary could become "the happiest barrack" in the Soviet Bloc. Limited modernization, through, would happen in from the mid 1970s onward to replace older stocks of military equipment with newer ones to enable the HPA, in a small way, to honor its Warsaw Pact commitments.
