I see that some want carriers but think the US ones are too big. Vel there are smaller options, the Tarawa class LHA genreral purupose assault ships that can carry helos or VTOL aircraft like the Harrier, have a look at http://www.spear.navy.mil/ships/lha4/facts.html
they are about 247m, 40m longer than the Brittish Invicible class (206m) look at http://british-forces.com/rtw/ships/aircraftcarriers/invincible.html
for more info.
B.T.V. the Russians have the Kiev class carriers (about 270m) (for those who want more russian units).
And please, give the Blackhawk MG a second machinegun on the right side. Also give the Blackhawk SUU (minigun) pods instead of the useless droptanks.
