For Random Books 18: Freidman's Royal Navy

The review introduces four large Friedman studies as useful foundations for researching British carriers, cruisers, submarines, destroyers, and frigates.

A modernized Daring study shows how a British 4.7-inch mounting, fire control, torpedoes, anti-submarine weapons, speed, and endurance pushed a fleet escort beyond practical screening-ship size.

Large fold-out design plates distinguish the submarine volume from some of Friedman's other books and invite comparison with the John Brown design studies.

A contemporary assessment praises the A-class boat's diving and handling while identifying limits imposed by reused engines, wartime materials, cramped torpedo spaces, light armament, and imperfect radar.

The assessment praises a cleaner separation of command and ship-handling functions, notes limits on fitting American fire-control equipment, and points toward closed-cycle propulsion and smarter torpedoes.

A contemporary assessment separates reliable American equipment from British boats' combat qualities and singles out the German 500-ton U-boat as an exceptional wartime submarine.

A British study found that triple 8-inch turrets demanded heavier armament, ammunition, magazines, and armour, forcing direct tradeoffs with machinery protection, torpedoes, steering protection, and endurance.

A 1924 twelve-gun cruiser study found that the machinery required for 34 knots consumed nearly all the weight freed by deleting the bulge, leaving unacceptable magazine protection.

Friedman's study shows why a proposed 23,000-ton treaty limit could deliver roughly fifty aircraft and thirty knots yet still fall short in underwater and bomb protection.

A four-hull paper fleet would often yield only three available carriers because of refits, making five ships with four commissioned or six smaller treaty carriers more resilient choices.

A technically workable British carrier limit still had to fit the 5:5:3 treaty ratio and leave Japan enough tonnage for an efficient additional ship.

The conclusion warns that ship limits negotiated for present requirements can become liabilities as technology and operational needs change.
