P-8A Poseidon, Boeing’s aerial system that destroys submarines from long range

The United States continues to invest money in the development of more spectacular and innovative military vehicles than other world powers. is the last P-8A PoseidonA High Altitude Anti-Submarine Warfare Weapon (HAAWC) that will be part of your naval equipment.

the aircraft is capable of converting MK 54 lightweight anti-submarine torpedo in long-range weapons and is manufactured by Boeing. The company says that the US Navy has given initial operational capability, so the P-8A Poseidon is now available for service.

it’s about a Air Launch Accessory (ALA) Which allows the Mk 54 torpedo to deploy two wings and go to its target with a GPS navigation system with a range of 65 km. As such, it turns them into long-range systems, capable of course correction in mid-flight until the submarines reach them. Once there, the ALA drops a torpedo with a parachute where the target is.

This is an operation of the P-8A Poseidon.

The Spanish Defense has this type of drone since 2019.

“We’re excited to offer greater flexibility and capability by launching to higher altitudes and longer ranges than ever before,” said Dwayne Donnelly, HAAWC program manager at Boeing.

China proposes supersonic torpedo

While the United States already has its own HAAWC long-range anti-submarine weapon ready to buy, Chinese researchers claimed in September a supersonic aerial torpedo, As he explained, it had a new boron-powered motor that allowed it to travel at double the speed of sound and reach 100 meters per second underwater.

Li Pengfei, a researcher at Changsha National University of Defense Technology (Hunan), and his team detail how their new power and propulsion system “It can significantly improve the penetration capability of the missile”, Their project was published in the Journal of Solid Rocket Technology of the Chinese Astronautical Society and circulated through the South China Morning Post.

The Chinese missile is 5 meters long and can fly at 2.5 times the speed of sound. The study mentions that it reaches an altitude of 10,000 meters for about 200 kilometers and then descends to the sea level for 20 kilometers. When the weapon is positioned about 10 km from its target, it becomes a torpedo when immersed in water, capable of reaching speeds of up to 200 knots (over 100 meters per second).

The researchers comment that the weapon can quickly change course and can be submerged up to 100 meters deep. This is achieved thanks to cavitationA phenomenon that occurs when a large air bubble forms around the missile, reducing the resistance of the water on the surface of the device.

“The hybrid ramjet uses a solid fuel-rich propellant, which is burned by outside air or seawater entering the system to generate a high-temperature gas. and generates thrust through the nozzle -they report in their study-. It has a high specific impulse and a simple structure making it an ideal power source for a hybrid anti-ship missile.”

Boron, which is the fuel they use, typically accounts for about 30% of the total fuel weight in an aerial missile. Even then, Chinese missile uses double to increase thrust, which may hinder its mass production, ignition and combustion control. Despite this, they hope to resolve these potential roadblocks as they move forward in the investigation.
