The first two models of light cruisers presented are the British HMS Enterprise, an Emerald-class light cruiser, and the Italian Giussano-class light cruiser Bartolomeo Colleoni. The HMS Enterprise is capable of speeds up to War Thunder Golden Eagles 33 knots, boasts good armour, and is armed with seven 152mm main cannons, as well as anti-aircraft cannons, machine guns, and even torpedo tubes. 

The Bartolomeo Colleoni is slightly faster at 37 knots and surpasses the HMS Enterprise in armament, as it offers eight 152mm main cannons plus six additional 100mm long range cannons. Its protective capabilities, however, are considerably weaker, with only 24mm of hull armour in comparison to the 76.4mm offered by the British ship. Captains of the Bartolomeo Colleoni will also have to keep an extra eye on the sky, considering the noticeably weaker anti-air defense compared to the HMS Enterprise. The latter, however, still remains susceptible to attacks from daring torpedo bombers, given that the British ship will need more time to maneuver than the faster Italian vessel.
