SHIELD Helicarriers from Marvel and the Movies

We are now starting to get some pictures from the next Captain America movie that will be coming out in 2014.  The one picture included with this post appears to show Two new Helicarriers (hull #s 42 and 65) in drydock.

These appear to be 'improved' versions of the one that we saw in the 2012 Avengers movie in that the four side fans appear to be fixed in place.  No more raisng/lowering the side fans when the ship is in the ocean.  Deck layout still appears to be the same.  Top angle flight deck is for landing and the lower, straight deck is for take-offs.  These new Helicarriers also appear to show some extra power for lifting off.  Repusor (ala Ironman) technology?

Background information is that Tony Stark/Stark Industries built the huge flying ships for the extra-governmental intelligence and defense agency known as S.H.I.E.L.D. (Strategic Homeland Intervention, Enforcement and Logistics Division).
