HMS Tiger (C20) was a member of the Tiger-class light cruisers. She was ordered for the British Navy during World War II and completed after the war. HMS Tiger entered service in 1960, serving in the Far East and then with the Home Fleet before retiring at the end of 1966. Before returning to service in the early 1970s, she was converted to a "helicopter and command cruiser" and outfitted with guided missile anti-aircraft defence. She served until 1978, when she was placed on reserve and designated for disposal. There were plans to bring her back into service for her flight deck capacity during the Falkland War, but they never materialised. HMS Tiger was eventually sold for scrap in 1986.

Introduced in Update 1.87 "Locked On" as a reward for the "Battlefield Engineer" event, HMS Tiger is an unusual cruiser. She has limited firepower and thus lacks the strike punch of contemporary light cruisers. This is partially offset by her extremely fast rate of fire. Her access to radar fire control makes her a very dangerous threat to enemy vessels, as she can compute firing solutions much faster than traditional optical rangefinders and can operate in the presence of smoke. Her quick rate of fire also allows her to adjust her fire much faster in response to enemy vessel movements, making it more difficult to consistently evade her shells. HMS Tiger is also very good at anti-aircraft defence, with access to both aircraft-tracking radar and proximity-fused shells for both primary and secondary armaments. On the other hand, she is less well protected than other modern British light cruisers, with a thinner main belt, poorer turret protection, and an exposed ammunition magazine. Players should avoid using her to engage heavier-armed vessels because they can easily penetrate the armour and detonate the ammunition magazines.
