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.
