The S/R-2 was equipped with a fast deploying drogue chute which kept the seat from tumbling and helped decelerate the seat/man package to a speed where the parachute deployment forces were more within the range of human tolerance. Another change that occurred over time was the change to a gas operated retractor for the shoulder harness to position the occupant prior to the catapult stroke. The concept was to set the occupants back against the seat structure and hopefully straighten his spinal column before the G load increased. The canopy jettison system was also modified in concert with the delay charges to provide a faster egress from the aircraft. One other point to mention in regard to the S/R-2 is that the emergency oxygen system was optimized for high altitude use.

In order to reduce parachute opening times for low altitude ejections, a gun deployed parachute made by Weber was incorporated. The chute includes an integral drogue gun which fires a slug out at a 45 degree angle over the crewman's left shoulder. This parachute was also installed on some of the C-2 seats, so the presence of the gun deployed parachute alone does not indicate the seat is an S/R-2. The parachute firing mechanism was activated during seat separation and included an aneroid system to prevent the chute from deploying above 15000 feet.
