The US Navy announced in May 2018, that it was restarting the 2nd Fleet to oversee the western Atlantic Ocean, including the North Atlantic and the US East Coast.
The decision comes after several years of tensions between NATO members and Russia — and several warnings from Western officials about growing Russian naval activity , including more sophisticated and more active submarines.
NATO has responded in kind, with a special focus on antisubmarine warfare — a capability that has waned among Western navies since the end of the Cold War.
For NATO members and other countries, augmenting antisubmarine abilities means not only adding ships but also advanced maritime-patrol aircraft to scour the sea. A number of aircraft on the market fill this role, but the US-made P-8A Poseidon is among the most sophisticated. A P-8A Poseidon "What it can do from the air, and tracking submarines, is almost like Steven Spielberg," Michael Fabey, author of the 2017 book " Crashback ," about China-US tensions in the Pacific, told Business Insider in early May 2018.
"I went up on a training flight," he said, "and basically … they could read the insignia on a sailor’s hat from thousands of feet above."
"It’s not the aircraft itself of course," he added, but "all the goodies they put in there." ‘The best ASW … platform in the fleet’

In 2004, the US Navy picked the P-8A Poseidon to succeed the P-3 Orion, which had been in operation since the 1960s. The first Poseidon entered service in 2013, and more than 60 are in service now.
The jet-powered P-8A is based on Boeing ‘s 737 airliner, but it is specialized to withstand more strain, with aluminum skin that is 50% thicker than a commercial 737. Every surface is equipped for deicing.
A commercial 737 can be built in two weeks, but a P-8A takes roughly two months. Navy crew members on board a P-8A Poseidon. It has a ceiling of 41,000 feet, and, unlike the P-3, is designed to do most of its work at high altitude, where it has better fuel efficiency and its sensors are more effective. The Poseidon’s top speed of 564 mph is also 200 mph faster than the older Orion, allowing it to get to its station faster and reposition more quickly.
Among its sensors is the APY-10 radar, which can detect and identify ships on the surface and even pick up submarine periscopes. It can also provide long-distance imagery of ports or cities and perform surveillance along coasts or on land.
An electro-optical/infrared turret on the bottom of the plane offers a shorter-range search option and can carry up to seven sensors, including an image intensifier, a laser rangefinder, and infrared , which can detect heat from subs or from fires.
