Ship project history: The well-known Holland boats, built in the USA and assembled in Canada in 1916-1917. One of the most successful projects of time. Single-hulled.

Modernizations: 1920, all survived: + 1 x 1 - 76/30 Armstrong 1914.

Naval service: H5 was sunk 16/4/1918 by mistake in Southern Adriatic by British sister-ship H1 (temporarily called HB1, not to confuse British and Italian submarines). H8 was sunk at La Spezia 5/6/1943 by Allied aircraft. H6 was captured by German troops in September, 1943 and scuttled by them.
