USS NARWHAL FH - 700 - hollow

USS NARWAHL (SSN-671) was a modified Sturgeon class nucleared powered fast attack submarine in the US Navy.   She was 22ft longer than the standard Sturgeon submarine.   She had a prototype nuclear power plant that was later used in the Ohio class submarines.  She was reportedly the "quietest submarine" until the Ohio and Seawolf classes came on-line.  The "hump" was reportedly added for testing new thin-line towed arrays.
No unclassified drawings or photo exist of her configuration below the waterline.  The Starboard towed array tube is conjectured.
Scale: 700
Full Hull
Hollow model w/ 4mm vent holes.
