ALANTIC OCEAN (Dec. 5, 2007) A 11-meter rigid hull inflatable boat (RHIB) descends to the water off the Virginia Beach coast after a successful launch of the Maritime Craft Aerial Deployment System (MCADS). Special Warfare Combatant-craft crewmen (SWCC) and parachute riggers from Special Boat Team (SBT) 20 work together to deploy an 11-meter RHIB 3,500 feet from the rear of a C-130 during an MCADS drop. SWCCs free-fall jump after the RHIB, and prepare to get underway once they reached the water. SBT-20 is one of the few units in the world with this capability.
