>>Don’t forget the Hoover (S-3 Viking)!
Speaking of which, I just realized the other day that the S-3 fleet had been retired a decade ago. WTH has replaced it for the ASW mission? Nothing?
Helicopter Anti-Submarine Squadrons
Helicopter Anti-Submarine squadrons are composite squadrons usually made up of four to six SH-60F Seahawks and two to four HH-60H Seahawks. Both Aircraft are Carrier-Based. The SH-60Fs primary mission is Anti-submarine warfare (ASW) defense of the inner zone, which includes detection, classification and destruction of hostile submarines. HH-60Hs primary mission is combat search and rescue (CSAR), Naval Special Warfare support (NSW) and anti-surface warfare (ASUW).
Helicopter Anti-Submarine (Light) Squadrons
Anti-Submarine Light squadrons each operate between six and fifteen SH-60B LAMPS III helicopters. The SH-60Bs primary mission is to provide fully mission capable detachments aboard cruisers, destroyers, and frigates assigned to the Fleet. These detachments are an integral part of the ships weapon system, extending the ships under-sea and anti-ship warfare capabilities beyond the horizon. As of 2003 all Helicopter Anti-Submarine (Light) Squadrons are schedule to be redesignated Helicopter Maritime Strike Squadrons. This change will reflect the switch to the MH-60R Seahawk and the squadrons new multi-mission capability.
Helicopter Maritime Strike Squadrons
Helicopter Maritime Strike squadrons operate the MH-60R Seahawk. The first operational fleet squadron to receive the Romeo is HSM-71 in fiscal year 2008. The new squadron designation was created to reflect the MH-60Rs multi-mission capabilities. Eventually all Anti-submarine (Light) squadrons will transition to the MH-60R and be redesignated HSM.
