Why get the Me-262A-2a when it was a crappy plane? It was virtually worthless as an attack plane and couldn't maneuver like the Me-262A-1a. The Storm Bird built up too much speed in diving attacks, making the plane almost uncontrollable and very inaccurate when making dive attack runs. It was also gimped in the guns department with only 2x 30mm cannons. The only ordnance it could drop with any sort of accuracy were cluster munitions (and you don't have to be accurate with these ordnances) dropped using horizontal attacks at low level.
