Design

With nuclear-armed Russian submarines an increasing threat in the 1960s, the Navy decided it was high priority to acquire a reliable, modern anti-submarine aircraft to replace the aging S-2 Trackers. The new aircraft had to carry "more bombs farther." Many companies, including Grumman, McDonnell Douglas, and Lockheed built prototypes.

Lockheed was awarded the contract in 1969 in coalition with Vought and Univac. The Lockheed company was to build the fueslage, while Vought designed the engines, landing gear, and the folding wings and tail. Univac was responsible for the powerful onboard computer.

Service

On February 20, 1974 the aircraft first equipped VS-41 aboard the John F. Kennedy (CVN-67). In the 1990s, after the collapse of the Soviet Union, many S-3s were modified to become tanker aircraft and transport planes. During the first Gulf War, they were useful as tankers, transports, and scout aircraft. However, one airplane launched a Maverick laser-guided missile, destroying an Iraqi target, the only instance where an S-3 was used in combat.[1]

"Navy One"

On May 1, 2003, George W. Bush rode in an S-3 to the USS Abraham Lincoln (CVN-72), the only aircraft ever to use the callsign "Navy One." The aircraft was piloted by Commander John "Skip" Lussier, the commander of VS-35.

Retirement

The last S-3 will be replaced in 2009.
