Ship project history: These ships were distinguished from previous class only by new 50-cal guns. Horsepower was increased slightly to offset the rise in displacement, but a slight reduction in beam and draught, as more length helped as well. 305mm Mk.XI guns were not successful and had very short barrel life and reduced accuracy at long range. As in Bellerophons the aft fire control position was useless because of smoke interference.

Protection: Main belt has 254-mm (tapering to 203-mm at the lower edge) thickness between barbettes "A" and "Y", 178-mm between barbette "A" and stem (last 10-m part from the stem was 51-mm), 64-mm between barbette "Y" and stern; its height was 2.08 m. Upper belt over 254-mm main belt was 203-mm. Both belts closed by fore 203 - 127-mm and aft 203-mm bulkheads. Second fore 102-127-mm bulkhead was at the end of 178-mm belt. Main deck was 32-mm between barbettes "A" and "Y", 44-mm middle deck with 44-mm slopes closed citadel. Lower deck was 76 mm aft from barbette "Y" and 38-mm fwd from barbette "A". Outer sides of barbettes "P" and "Q" were 254-mm.

Modernizations: before 1914, all: lowering the topmasts; - 2 x 1 - 102/50 (roof of "A" turret)

1915 - 1916, all: + 2 x 1 - 76/45 20cwt QF Mk I

1916 - 1917, all: clinker screen on the fore funnel was mounted (Collingwood received clinker screen on the after funnel also), torpedo nets were removed; - 2 x 1 - 76/45, 1 - 450 TT (stern) (stern); + 1 x 1 - 102/50 BL Mk VII (AA)

1918, Collingwood: + flying-off platforms on "A" & "Y" turrets for Sopwith Pup and 11/2-strutter

1918, Collingwood, St. Vincent: bridgeworks and control tops were enlarged, superstructure was build up, searchlights were regrouped.

Naval service: Collingwood grounded on uncharted rock off Ferrol in February 1911. Vanguard blew up at anchor in Scapa Flow 9/7/1917 due to faulty ammunition exploding. 804 lost. Collingwood since 1918 served as gunnery TS. St. Vincent was paid off into reserve in 1919 and served as gunnery TS until finally paid off late 1919.
