Weapons loads, generally limited to 1,800 kg (4,000 pounds), are transferred from the supply ship to the flight deck of the amphibious ship. The decided advantage of a VERTREP is that it can effect replenishment without ship-to-ship connection. 188:
Lift capabilities of helicopters are reduced by adverse wind conditions or high temperature or humidity. Pre-loading of pallets is necessary for rapid transfer, and requires advance knowledge of weather conditions and special care to secure light items which may otherwise be blown out of containers.

VERTREP helicopters are equipped with a cargo hook from which may be suspended either special ordnance slings or conventional cargo nets for less sensitive loads. A normal load is two to four pallets, depending on weight. The load is placed in position on the deck of the receiving ship by lowering

Ships without large flight decks or support equipment like forklifts are often unable to break down palleted loads and transfer them off of the receiving deck as rapidly as the helicopter can deliver another load. VERTREP supply ships carrying more than one helicopter can simultaneously make

While popular in use, VERTREP is considered relatively dangerous (as compared to other replenishment methods) as it involves danger to the loading personnel due to the helicopter and the load, and in turn, potential risks to the helicopter due to
