Hello guys, in this post I am going to suggest the SH-60K, a successor of the SH-60J ASW/SAR helicopter for the JMSDF. Currently the Japanese Heli tree is stuck with very little vehicles due to the JGSDF utilizing only a handful of attack-helicopters. Therefore, I would like to propose a vehicle from the JMSDF which does have Anti-Vehicle capabilities to improve the vehicle lineup while giving the Japanese Heli tree a taste of originality.
Also, since the MH-60L DAP has been added in game, the model should be relatively easy to work on compared to making a new one from scratch.
History

The SH-60K is an upgraded version of the SH-60J. It was developed to replace the SH-60Js that would reach its end of service life at 2005. Upgrades were made in order to respond to the trend towards quieter, anechoic, and faster submarines while also being able to keep up with the much-diversified SDF’s missions such as disaster response.
Prototype development for the SH-60K had started from 1997 at Mitsubishi Heavy Industries and 2 prototypes were delivered to the Japanese Defense Agency (now known as the Ministry of Defense). After testing by the government, its adoption was admitted in March 2005 and entered service in August 2005. By 2023, the SDF has 73 SH-60Ks with 10 SH-60Js.
The SH-60K has numbers of upgrades from the SH-60J but the biggest is its Main-Rotor-Blades. The blade is made out of composite materials except for the tips and leading edges which are made out of metal. The wing tip shape has also been changed for better aerodynamic characteristics when hovering. The armaments have also been upgraded and can be equipped with AGM-114M Hellfire II missiles and Type 97 Torpedoes too. Also, AN/AAR-60 MAWS and AN/ALE-47 Countermeasures Dispenser Systems had been equipped to improve its survivability. In order to compensate for the weight increase, the engine was upgraded to the T700-IHI-401C2. These upgrades have increased the Designed Max Weight and cabin size (30cm in length, 15cm in height)
On December 2023, completion of development of the SH-60L, an upgraded version of the SH-60K had been announced by the MoD.

I think that the two torpedoes may not need to be implemented, though it can be ever if modern ships equipped with helicopters would enter the game.
