60s are more spread out, depends on what type of 60 you get:
HSL (SH-60B)
NS Mayport - East/RAG
NAS North Island - West/San Diego/RAG
MCBH Kanehoe - Hawaii
Atsugi - Japan
HS (SH-60F/H)
NAS Jax - East
NAS NI - West (RAG location)
Atsugi (I think, don't know about selection from HTs)
HSC (MH-60S)
NS Norfolk - East/RAG
NAS NI - West/RAG
Guam
HM (MH-53E)
NS Norfolk RAG
NAS Corpus Christi
Thats what you can select out of HTs. Of course there's some station SAR helos you can fly on your shore tour later on, but the above is what you'll see comin out of HTs. HSM, with the MH-60R, is also starting up in San Diego and will be the eventual replacement of HSL.
