Underwater Submarine Hull Collision

One complete 3-second underwater game sound effect: a diving exploration capsule strikes a submerged wreck with one heavy muffled metal impact, followed by a low metallic hull groan, then sparse soft bubbles and silt dispersal settling into quiet. This must be one continuous event with one main collision only, no second impact, no montage, no music, no voice, no ambient background and no clean water splash. Use a thick enclosed underwater perspective and a natural continuous decay.
