Which LCU version is this?
LCU 1610 - LCU 1624 built in 1960 (or 1970?)
LCU 1625 - LCU 1625 LCU-1466 type
LCU 1626 for foreign service - not the drawing
LCU 1627 - LCU 1679 built 1967-76; bow and stern ramp (are they both shown on the drawing?? The bridge seems a little different...)
photos of p.e. LCU-1645, LCU-1631, LCU-1650, etc.
