Development and History

Particulars

Its overall length including 4.5-in long pistol was 17 feet, 7.4 inches (see Plate).

Manufacture and Use

The raw Mark VII torpedo was first ordered in 1910-1911; oddly, this is after the Mark VII* and Mark VII** variants in 1908-1909. More careful reading is required.

Mark VII*

Forty S.L. torpedoes were ordered in 1908-1909, but were somehow only reported the following year.

Mark VII**

Some 53 Hook Bracket and 143 Side Lug specimens were ordered or given heaters in 1908-1909 – the source needs to be read more carefully.^{[Citation needed]}
