Project history: The Passaic class were enlarged and improved Monitors. There was a less pronounced overhang than Monitor, and the shape of the lower hull and its junction with the 'raft' were improved. Ventilation was better, and an 5.5m high funnel was fitted, protected by 8x25mm armour to a height of 1.8m. The pilot house was located on top of the turret but did not rotate with it, and had 8 x 25mm sides and a 2 x 25mm roof. The 381mm gun muzzle did not project from the turret which was 6.4m internal diameter, and a smoke box was fined to keep smoke and fumes out. As a result the 381mm gunners could not see the target and had to aim via the 279mm or 203mm. The pendulum port-stoppers were replaced by crank-shaped forgings needing a 90° turn. Extra protection was added to some of the class as a result of experience at Charleston. Rings were fitted round the bases of turrets and pilot houses, the roofs of the latter were increased to 3 x 25mm and an extra 50 tons of 25mm deck plating added over magazines and machinery spaces.
Comanche was built in Jersey City, taken to pieces and sent to California on board Aquila which sank at San Francisco 14.11.1863. The sections were salvaged and reassembled, and Camanche launched as given above.
Ship protection: As in Monitor all the armour was built up from 25mm plates (deck 13mm) and the side was reduced to 102-76mm below water.
Modernizations: late 1863, Passaic: - 1 - 279/15; + 1 - 203/18 150pdr Parrott MLR
1864, all survived: armour of pilot roof was increased to 76mm, 25mm armour was added to the deck over magazines and machinery; + 2 x 1 - 76/11 12pdr SB field howitzers
by 1865, Catskill, Montauk, Nahant, Nantucket, Jason: - 1 - 279/15; + 1 - 381/11 short Dahlgren SB
by 1865, Lehigh, Passaic: - 1 - 203/18; + 1 - 381/11 short Dahlgren SB
Naval service: Weehawken foundered in a gale off Morris Island, Charleston 6.12.1863, from shipping too much water through open hatches and the hawse pipe before proper measures were taken, and it may be noted that Lehigh survived a Force 10 gale off Cape Hatteras when the water was more than 1.2m over her deck. These monitors were very vulnerable to mines and Patapsco sank 15.1.1865 in about 15 seconds after striking a mine with 27-30kg cannon powder charge which exploded 11m from the stem. Passaic served as receiving ship till 1878 and in 1895 she was loaned to Naval Militia. She was recommissioned for Spanish-American war but soon decommissioned and sold for scrap a year later.
