Orlikon MK 10.jpg [ 248.66 KiB | Viewed 17020 times ]
The England AOS book indicates that these DE's were originally equipped with the 20 MM MK 4 Orlikon. This had an elevating mechanism operator and required an additional crew member. My unproven assertion was these were replaced, in the case of Whitehurst with the MK 10 and MK 14 sight either before or after her Pearl Harbor post Kamikaze refit. I have modeled both units so it's not a choice of convenience.

Hedgehog, a spigot mortar defied by the British, was a very effective weapon compared to depth charges. England used hers to kill all six submarines. The mechanism was provided with a tilting mechanism for each row which compensated for roll. The angling and firing was set to provide an oval pattern about 140 feet across with all projectiles arriving at the same time. Each projectile was contact fused and contained 30 lbs of TNT. Contact and explosion of a single projectile seemed to be enough to cause eventually fatal damage to a submarine. Sinking of the projectile was rapid, about 4.5 seconds per 100 ft. Post war Whitehurst was fitted with two Hedgehog units, trainable, on the O1 level in the place of the Orlikons located there.

Whitehurst was fitted with 8 K guns aft which could throw either the MK 6 Ash Can or the lighter MK 9 streamlined depth charge. Range was controlled by varying the propulsion charge. These are just the racks as the K guns modeled in 1:144, tip over if not adhered to the surface. A davit was associated to assist loading spares into the rack, not installed.
I showed the Goopy Gray model, though the Rapid Black resin is slightly more detailed, but hard to see without paint.
