CA3 PDAB Airburst Cannon
Posted: Thu Jul 24, 2008 9:42 pm
Name: CA3 PDAB (Cannon Assembly Mk. III, Pre-Determined Air-Burst)
Type: Single Shot Pneumatic Cannon, Interchangeable Upper Section
Loading Method: Muzzle Loaded
Barrel Type: 2' by 3" Sch40
Chamber Type: 2' by 2" Sch40 (2x)
Operating Pressure: 30psi-100psi
Fire-Control Sys: FA-E1B NCS
Ammunition: 75mm M2 Shell NAABFW, 75mm 'Skipper' Anti-Materiel
# of Valves: 1
Type of Valves: Stock Orbit Watermaster 1in Sprinkler, Solvent connectors
Sights: None
Projected Improvements: Build additional upper Modules, including Breach Loaders, Small Diameter Barrels, and others.
The CA3 PDAB is a cannon developed under the WC-AB Project to fire specially designed 75mm airburst shells. Designed with ease of reloading in mind, the entire barrel and cable compartment are secured to the valve/chamber assembly via a union. This allows for the use of a number of different barrels and ammunition, but the main feature is its ability to fire a specialized airburst shell, the 75mm M2 Shell NAABFW (Non-Adjustable Air Burst Flour Warhead). Secured to the cable compartment with a large nut, the cable pulls on the shell when it pull tight, triggering it to open. Its secondary armament, the 75mm 'Skipper' Anti-Materiel round, is nothing more than a long water bottle filled with water. Launched at 90psi, it travels about 50' before hitting the ground and skipping, maintaing sufficient kinetic energy to knock over sandbags, useful for taking out unmanned fortifications. It uses an upgraded variant of the FA-E1 NCS, the FA-E1B. The 'B' model makes up for the shortcomings of the initial model, adding a second battery and a SP-ST safety.
EDIT July 27: Sorry for the confusion about the pictures, everyone. I did indeed take the pictures when I said I did, I just became unexpectedly busy in the last two days. Sorry about any confusion.
