Navy Aircrew Common Ejection Seat (NACES)


The Navy Aircrew Common Ejection Seat (NACES) is the common ejection seat designed for incorporation into the F/A-18, EA-18G and T-45 aircraft. The ejection seat is the primary means of aircrew escape from disabled aircraft and it provides the seated platform for the aircrew, in-flight aircrew restraint, and necessary cockpit interfaces to meet mission performance. Since 1991, more than 2,300 seats have been delivered and fielded both domestically and internationally.


Supplemental capability efforts to include aircrew endurance improvements and the Joint Helmet Mounted Cueing System upgrade are currently being fielded. NACES has a 100 percent successful rate for ejections within the ejection envelope with over 100 lives saved since fielding.
