Anti-Submarine Mortar Mk 10

The triple barrel Anti-Submarine Mortar Mark10 was located to the rear of the after funnel on the Tribal Class frigates. It sat in the mortar well with the mortar handling room on the left of the photograph behind the plated doors. The mortar was laid horizontally against these doors and the mortar projectile bombs were then loaded into their individual tubes from there.
Once loaded, the mounting was basically ready to fire once it received computed information telling it where to point in elevation and training.
When the mounting was horizontal, the platform with the guard-rails on the right enabled the loaders to insert explosive firing cartridges at the base of the mortar tubes after the mortar bombs were loaded into the tubes.
From what I can remember, it could fire either single shot or a salvo of all three mortar bombs.
It was a spectacular weapon to watch when fired. The slow graceful arc of the projectiles followed by the shock wave through the water initially, then the noise of the explosion, and then the huge eruption and cascade of water. Oh,...and most usually fish on the menu for several days afterwards!!

As a footnote: the curved grey plates towards the rear are man-handle-able cover plates for the flight deck.
When the ships Wasp helicopter landed, the flight deck itself lowered down into the hangar with the helicopter strapped down onto it. The Wasp was then stowed/stored away inside the hangar. This of course left an open sky, so these curved metal plates covered over the hole left behind by the now missing flight deck.
