Note the absence of masts and cargo booms fore and aft and the two open side-loading ports amidships through which she loaded her cargo of vehicles and parcels.

USS Miantonomah (CM-10)

Near the Norfolk Navy Yard on 29 April 1944 after a major reconfiguration of her minelaying facilities.
Two new mine rails with large chutes in sponsons have been added outboard of the original two rails, whose chutes have been reconfigured and lowered. Other modifications include the addition of a lattice radar mast just forward of the stack.

USS Monadnock (ACM-10)

Photographed from USS Holland (ARG-18, ex AS-3) at Sasebo, Japan, in October 1945 with a 173-foot PC alongside.
The stern does not show the large sponsons aft added to her sister in 1944 and she probably did not receive this alteration. Her foremast has been moved to a position behind the bridge, probably during her conversion in mid-1945 to an auxiliary minelayer (ACM) and minesweeper support ship.

USS Monadnock (ACM-10)

Probably at San Francisco shortly after her return there in April 1946.
Note the foremast in its new position behind the bridge, the new 40mm quadruple mount forward, and the extreme weathering to the hull paint on the bow.
