Navy adopting Army's External Stores Support System???

ATLANTIC OCEAN (July 14, 2010) Marines assigned to the visit, board, search, and seizure team of the 26th Marine Expeditionary Unit (26th MEU) fast-rope from an MH-60S Sea Hawk helicopter onto the flight deck of the Military Sealift Command fleet replenishment oiler USNS Leroy Grumman (T-AO 195) during a composite unit training exercise (COMPTUEX).

I saw this photo on the Navy website and noticed that this helicopter is sporting the Army's External Stores Support System.  Every SeaHawk that I had seen before wore the Navy's unique store system which was much lower on the fuselage.  Is this change common place or is this simply a trial?
This would definitely make the SeaHawk only one step away from becoming a true BattleHawk, able to influence warfare in the littorals.  Maybe NAVAIR is listening????
