Thanks, CV32 and sorry to later. 2350, afloats go to contacted position in high speed. P-3C decrease speed and altitude to detect with MAD. Sub recognize P-3C with ESM, so sease snorkel and dive to Int 1 2353, DD-130 Matsuyuki departs from a squadron to launch a helicopter. P-3C fails MAD detecting because it's area is very narrow.

You are the Commander, Training Squadron of Blue Force. TS departed the last port of the ocean training cruise, and go to home port. But, Blue and Red nation skirmished accidentally in the Alfa islands yesterday. The prospective course of TS is now in a tense atmosphere, so the joint staff office detached one P-3C MPA to your force. 2350 in local time.

But P-3C had to depart here in 20 minutes because of fuel. You command your ships, a helicopter, and MPA, keep contact and identify it. You CAN'T do preemptive strike, definitely. Your force: Training vessel Kashima(TV-3508) Training vessel Setoyuki(TV-3518, ex-DD-131) Destroyer Matsuyuki(DD-130) Patrol Helicopter 1 SH-60J Patrol Aircraft 1 P-3C(with in 20 minutes) (Red force: 1 Yuan class Submarine) to be continued...

Thanks to introduce the article. It`s very difficult that model it collect. So, I think it's almost nearly idea that if there are some vehicles that have multistatis sonar capability, their sonar range extend.

How do you do? I'm glad to join this community ,and meet the players of Harpoon4. I'm from Japan, and Japanese Defense Navy will commission the new class Destroyer, we call 25DD(25 means Japanese financial year based on emperor). She will have Multistatic sonar capability, but Harpoon4.1 is not covered this new ASW technology. What do you think about how to evaluate that?
