Attachment (2) 618-WMEC_111_1_1_-_G.pdf

This document is a technical engineering drawing set for a 210' WWEC (Waterborne Working Evaluation Craft) Shell Expansion Framing and CVK (Centerline Vertical Keel) design. The drawings appear to be official Office of Naval Engineering schematics classified as "A" class documents, with drawing number 81340 and revision 111-001.

The document comprises three pages of detailed engineering plans and specifications. Page 1 contains the primary shell expansion plan with comprehensive dimensional annotations, structural details, and notations regarding material specifications and construction requirements. Page 2 provides detailed cross-sectional views and component details, including multiple sections (labeled as Detail views ranging from 2-D/2 through 12-E/2) that specify precise measurements, material callouts, and assembly instructions for various structural elements such as frames, stiffeners, and connections. Page 3 presents plan views showing the deck structure layout (including 2ND DK notation) with transverse references, framing locations, and dimensional grids for both longitudinal and transverse positioning. The drawings include comprehensive notation systems, reference markers, and engineering standards typical of naval vessel construction documentation. This appears to be a technical specification document for shipbuilding or maritime vessel construction purposes rather than a federal contract solicitation document.
