This car load is based on the Mark VII Naval Gun designed in 1939 and first used aboard Iowa-Class Battleships during World War II. Measuring 16" in diameter, these guns could fire a 2,400 lbs projectile up to 24 miles. They were last fired in combat during the 1991 Persian Gulf War. Each of these 68 foot guns weigh nearly 270,000 lbs and were shipped (breech first) across two(2) heavy weight flatcars with a third flatcar used as an idler.
Many of these guns were manufactured by Bethlehem Steel in Pennsylvania and transported via the Pennsylvania Railroad across three(3) F22 flatcars. These PRR F22 Flatcars are available as a 3-Pak kit from our Shapeways Shop or our website THENARCH.COM (Item #20101). There is also a box set that includes both the ‘Naval Gun Load’ and ‘PRR F22 Flatcar 3-Pak’ kit available from our Shapeways Shop or our website THENARCH.COM at a special price (Item #20102).
