11m ORC - ACV

The 11m Offshore Raiding Craft (ORC) is a development of the 9m ORC which is in-service with the UK Royal Marines. This 11m Aft Console Variant is designed to accommodate 14 troops all seated on Ullman Patrol XLT suspension seats. The coxswain and navigator are also seated on suspension seats.
This crafts primary role is the delivery of troops to shore in a fit to fight condition. A single weapon pedestal is fitted forward capable of mounting either twin GPMG or single HMG.
The ORC is designed with portability in mind. It can be transported and launched by trailer, features 4 lifting points inboard allowing it to be under slung from a helicopter and has tie down points for securing it to the deck of a ship or hold of an aircraft. The lifting points coupled with a painter release system means that the boat can be launched from a mother ship whilst underway.
