Princess Anne’s battery - bunker and 5,25 inch naval gun, Gibraltar – STL

 

Princess Anne’s Battery is located on the north side of the rock below the Great Siege Tunnels of 1782 and overlooking Gibraltar Bay and Spain. It was originally known as Willis’s Battery and later renamed Princess Anne’s Battery being named after the eldest daughter of George II; it was first armed in 1732.

The whole north side of the rock was heavily fortified during the 19th century with Princess Caroline’s Battery and Princess Amelia’s Battery a short distance to the west and Princess Royals battery to the east.

In 1942, during WW2 there was a proposal to install seven new 5.25” anti-aircraft guns on the rock, three of these eventually went to West Battery on the south of the rock between Windmill Hill and Europa Point. The other four guns were mounted in a rebuilt Princess Anne’s Battery with work being completed in 1956. The new guns were Ordnance QF 5.25” MKII on a 1B mounting and performed a dual anti-aircraft and coast defence role. Where 5.25” guns are deployed solely in an Anti-Aircraft role they have open backs (on a 1A mounting) but those at Princess Anne’s Battery were totally enclosed with the ability to return fire from an armoured ship as such were designated as an armoured turret. They were able to fire an 80lb shell up to 55,000 feet with a maximum horizontal range of 27,000 yards (13.5 nautical miles).

Three of the emplacements have a semi sunken magazine and machine room to one side, while that for No. 4 gun is completely underground.

 

This STL file is designed for FDM Printers and print with a 0.6mm nozzle at 0.3mm layer height. Epic scale will require 0.4mm nozzle at 0.2mm layer height for best finish.

Supports are needed for the gun.

 

The printed model measures approx.:

407mm x 231mm x 91mm @28mm Scale

268mm x 152mm x 52mm @00 Railway scale

204mm x 116mm x 38mm @15mm Scale

82mm x 46mm x 15mm @Epic scale

 

It is designed for 28mm table top games set in WW2 such as:

Bolt Action, Chain of Command and Konflikt ’47. It can also be used in games such as Judge Dredd, Dust 1947, Necromunda and Fallout Wasteland.

Now rescaled to for Flames of War, epic and 00 railways by popular demand.
