52100-1137-00B_SHOT LINE PROJECTILES.pdf

This is an engineering drawing from the Office of Naval Engineering showing technical specifications for a shot-line projectile for a .30 caliber rifle. The drawing (number 52100-1137-00B) provides detailed assembly dimensions and specifications for two variants: Assembly 101 (13-1/2" length) and Assembly 102 (15-1/2" length). The drawing includes multiple views and details of the projectile components, including a barrel slug, shot-line tie rod, and weight section. The general notes indicate that parts are to be manufactured in accordance with specified standards, with particular attention to surface finishes and tolerances. The drawing appears to be related to line-handling equipment used for ship-to-ship transfers, as referenced in the associated contract opportunity which seeks to procure these projectiles for the US Coast Guard.
