Didn't SHIELD just have those Hydra weapons because they were trying to use the Cube to make weapons? Actually, that's not a question. It was "Phase 2". The Nazis (and Hydra) lost the war. The Allies (and SHIELD- or people involved in the war, such as Howard Stark) go around collecting the enemy's technology to analyse and understand it. That includes the Cosmic Cube, and Hydra weapons I guess. So, SHIELD has these weapons available, and is trying to figure out how they work so they can make their own. Simple as that. It's already been explained. I think Steve understands this, and doesn't believe SHIELD to be an evolved version of Hydra.
