PCAS is a package of technologies designed to speed close air support to soldiers on the battlefield, enabling ground troops, Joint Terminal Attack Controllers (JTACs) and combat aircrews to share real-time situational awareness and weapons systems data. Executed in three phases, the four-and-a-half year program included flight testing during the first six months of 2015.
"The PCAS program was able to reduce close air support response times from nearly one hour to less than six minutes," said Tom Bussing, Raytheon vice president of Advanced Missile Systems. "By speeding critical information to decision makers, PCAS could save lives in the battlespace."
During the U.S. Marine Corps' Talon Reach V exercise in March, the program demonstrated end-to-end, fully digital weapons release of a Griffin missile from a modified MV-22 Osprey tiltrotor aircraft. In May, an A-10C Thunderbolt II attack aircraft and a joint terminal attack controller (JTAC) on the ground, both using PCAS' real-time digital communications and situational awareness capabilities, successfully employed 10 GPS- and laser-guided weapons in a second series of flight tests.
The PCAS system is designed to be platform-, digital radio-, sensor-, and weapons-class agnostic, and to be portable from platform to platform. The two main parts of the system are PCAS-Air, which consists of smart launcher electronics and a pilot tablet, and PCAS-Ground, which comprises the equipment used by the JTAC.
