Kawasaki P-2J Owashi (川崎 P-2J)
The Kawasaki P-2J is a Japanese patrol aircraft created in 1966 as a dance alternative to the Lockheed P-3C aircraft. In the years 1966-79, 83 P-2J aircraft were built, which were laid down by May 22, 1994.
History
When in 1959 the Kawasaki plant released the first Lockheed P2V-7 aircraft produced on the line, it was a very modern aircraft. However, the Japanese rightly assumed that this aircraft would need a successor due to the construction of more and more modern submarines. Therefore, in October 1960, a Japanese research team was sent to the USA to study the Lockheed P3V-1 (later P-3A) aircraft. It was stated that it would be a very modern aircraft, but at this point the purchase of it by Japan would be very expensive. In 1962, the Japanese estimated that the Lockheed/Kawasaki P2V-7 aircraft would be effective until 1975 at the latest, and the Grumman S2F-1 by 1970. For this reason, the PX-L project was launched, which was to select a successor for the P2V-7 and S2F-1 aircraft. The biggest problem of the project was the lack of financial resources caused by the fact that it was not taken into account during the Second Defence Capability Development Plan of 1960. In the second half of 1966, the JMSDF ordered Kawasaki, Mitsubishi and ShinMaywa to create an aircraft design for the PX-L project. Mitsubishi proposed to enlarge the Grumman S2F-1 aircraft and convert it into a high-wing aircraft. Shin Meiwa has made proposals to convert the PS-1 flying boat, which is currently being designed, into a land-based aircraft. Kawasaki’s proposal was to modernize the Kawasaki P2V-7 aircraft, as many as 7 different modernization options were proposed. The JMSDF also tested the modernization of P2V-7 aircraft proposed by Lockheed, Lockheed P-3A aircraft, Breguet Atlantic aircraft and the modification of the NAMC YS-11 aircraft. It was stated that the P-3A and Atlantcik aircraft were the best candidates, but too expensive, and it was also considered that the conversion of the YS-11 aircraft was comparable to the construction of a new aircraft and would have too poor performance. Finally, it was decided to propose the Kawasaki P2V-7 Kai (modified P2V-7), which was to improve the ability to detect submarines, process data, and modify the cabin to improve the comfort of the crew. The plane was also to receive more modern engines. At first, the Kawasaki plant wanted to rebuild two aircraft to the P2V-7 standard, but it turned out that there was a lot of research material and only one aircraft was enough. In March 1964, a research team was sent to the USA, which, in cooperation with the Americans, developed the required ASW equipment for the P2V-7 Kai. In 1965, for a price of about 637.3 million yen, the modification of the Kawasaki P2V-7 aircraft number 4637 to the prototype of the Kawasaki P2V-7 Kai aircraft began. In June 1966, the aircraft was completed, and on July 21, it made its first flight. After about a year of testing, the aircraft was introduced to the squad as the Kawasaki P-2J. In 1967, the National Defense Council decided to purchase 46 Kawasaki P-2J aircraft. The Third Defense Capability Development Plan initially called for the purchase of only 13 P-2J aircraft (but later the rest of the 46 Kawasaki P-2J aircraft were approved). The first (non-prototype) Kawasaki P-2J aircraft (number 4702) was delivered to JMSDF on September 30, 1969 and went to Air Development Squadron 51, where tests were carried out. The next P-2J (number 4703) was completed in January 1970. The production of one Kawasaki P-2J aircraft took one year and three months. In March 1970, the first squadron of P-2J aircraft began to be formed in the 1st Air Corps. The fourth Defense Capability Development Plan assumed the purchase of 36 more Kawasaki P-2J aircraft (which gives the number of 82 aircraft plus a prototype). At the end of 1978, the planes were placed in 5 air squadrons and 2 training corps. From January 1982, Kawasaki P-2J aircraft were gradually replaced by Kawasaki P-3C aircraft in almost all units. The last Kawasaki P-2J aircraft number 4783 was withdrawn from service on May 22, 1994. No Kawasaki P-2J aircraft was involved in an accident during the crash.
10th Yuyo Maru Incident
On November 9, 1974, the “10th Yuyo Maru Incident” took place. It was a collision of the Japanese gas carrier “10. Yuyo Maru” (gross tonnage: 43,723 tonnes) with Libyan Pacific Ares (gross tonnage 10,874 tonnes) in Tokyo Bay. On the ship “10. Yuyo Maru” after the collision at 1:37 p.m. there was a fire and then an explosion that killed 33 people and injured 7. Fire ships and tugboats from Tokyo, Yokohama and Kawasaki (a city, not an aircraft manufacturer) were quickly sent to the crash site. On 19 November, an attempt was made to remove the burning “10. Yuyo Maru”, but in the vicinity of the Kuroshio current, one of the explosions broke the tow ropes. On 21 November, a decision was made to sink the “10. Yuyo Maru” by the JMSDF, which on November 23 created a task force consisting of 4 destroyers (Haruna, Takatsuki, Mochizuki and Yukikaze), 1 submarine (Narushio) and 10 Kawasaki P2V-7 and P-2J aircraft. The sinking attempt began on November 27, 1974. From 13:45 to 16:05, Japanese destroyers fired at “10. Yuyo Maru”, firing 72 rounds of 127mm (36 at port and 36 at starboard), which caused a column of fire at 100 meters and smoke at 2,500 meters. However, “10. Yuyo Maru”, continued to float on the water. The next day from 9 a.m. to 10:20 a.m. on the “10. Yuyo Maru”, the JMSDF carried out air attacks using 127mm rockets and 150 kg bombs by Kawasaki P2V-7, P-2J and Grumman S2F-1 aircraft (12 rockets and 16 bombs were hit), but the carrier did not sink. At 11 a.m., the submarine Narushi attacked with 4 Mk.37 torpedoes in the direction of “10. Yuyo Maru”, of which torpedoes number 2 (port side) and number 3 (in the oore ship) were hit. However, "10. Yuyo Maru was still not sinking, so at 15:12 the ship “Yukikaze” fired a torpedo at the starboard side of the gas carrier, and at 16:16 the second torpedo at the port side. Only after that at 6:47 p.m. “10. Yuyo Maru” sink after 20 days of fire.

- Replaced 3,400 lbf (15 kN) Westinghouse J34-WE-34 auxiliary engines with Ishikawajima-Harima J3-IHI-7C engines, 3,100 lbf (13.7 kN) thrust
- AN/AQA-5 sonar installed

Summary
The Kawasaki P-2J is an interesting aircraft for Japan in War Thunder. This aircraft will be a very useful bomber with a huge bomb load, in exchange for zero self-defense capabilities. The Kawasaki P-2J can be added to the Tech Tree in the Kawasaki P2V-7 forder. This aircraft can also be a Premium or Event aircraft. I encourage you to discuss in the comments and to share your own knowledge on this topic.
Finally, I apologize for the linguistic and logical errors because unfortunately English is not my main language and I had to use google translator.
