The P-8A Poseidon, a variant of the Boeing 737 series of  airliner, takes over the role of antisubmarine warfare from the P-3 Orion, itself a derivative of an airliner, the Lockheed Electra. The P-8A brings new capabilities, endurance, and crew enhancements to the art form of maritime patrol, surveillance, and reconnaissance. The Poseidon also brings with it weapons such as antiship missiles, mines, torpedoes, and bombs. It can lay down sonobuoys to detect, track, and attack submarines that are quieter, deeper diving, and more stealthy than ever before. The ability to perform search and rescue, assist stranded victims of an incident at sea, and coordinate rescue efforts is unparalleled. The P-8A can connect to tactical networks to relay data it collects, or it can receive information and play a part in a larger operation involving several platforms, from surface ships to aircraft and ground facilities.

The General Dynamics F-111 was one of aviation history's most promising planes when it came out in the early 1960s. Despite a rocky service career, political changes in how the military acquired its weaponry, and the addition of too much new technology, the plane provided a credible frontline deterrent in the Cold War era and was used to great effect in the Vietnam War and Operation Desert Storm. Many of the challenges faced by putting the F-111—with all of its new systems—into service are now accepted as a normal outfit in modern fighter aircraft. Although the Navy did not accept the F-111B model, the Grumman F-14 Tomcat development program was significantly assisted by prior radar and missile system testing on the F-111B airframe. The F-111 was a hugely powerful aircraft and carried devastating weaponry, but was phased out by the USAF in the mid-90s, largely due to crippling maintenance costs. The aircraft remained in Australian service until 2010.
