HMS Gretna
1918 Hunt-class minesweeper

HMS Gretna was a Hunt-class minesweeper built for the Royal Navy during World War I. Completed in 1918, the ship was sold for scrap in 1928.
Design and description
The Aberdare sub-class were enlarged versions of the original Hunt-class ships with a more powerful armament. The ships displaced 750 long tons (760 t) at normal load and 930 long tons (940 t) at full load. They measured 231 feet (70.4 m) long overall with a beam of 28 feet 6 inches (8.7 m) and a draught of 7 feet 6 inches (2.3 m). The ships' complement consisted of 74 officers and ratings.
The ships had two vertical triple-expansion steam engines, each driving one shaft using steam provided by two Yarrow boilers. The engines produced a total of 2,200 indicated horsepower (1,600 kW) and gave a maximum speed of 16 knots (30 km/h; 18 mph). They carried a maximum of 185 long tons (188 t) of coal which gave them a range of 1,500 nautical miles (2,800 km; 1,700 mi) at 15 knots (28 km/h; 17 mph).
The Aberdare sub-class was armed with a quick-firing (QF) four-inch (102 mm) gun forward of the bridge and a QF twelve-pounder (3-inch (76.2 mm)) anti-aircraft gun aft. Some ships were fitted with QF six-pounder (2.2-inch (57 mm)) Hotchkiss guns or QF three-pounder (1.5-inch (37 mm)) Hotchkiss guns in lieu of the twelve-pounder.

Why this record matters
“HMS Gretna” is worth following because a concise public description often conceals a longer documentary argument. Here, Gretna, Hunt-class and minesweeper provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 6, 2026. The linked authority identifier is Q5632628. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1918 and 1928.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
