Front view of ARCS carrying two 25,000-lb steel fuel tanks across two 15’8”-ft-wide x 20-ft-long wooden decks.  Two fabric pouches (grey), each with three air-filled pontoons at ~ 1 psi, supported each deck.

SPoT successfully used similar ARCS during 2013-14 and 2014-15 to carry a refrigerated food module and an ISO container with tools and spare parts.
