Imperator Nikolai I began as a smaller derivative of Imperator Aleksandr II but grew to exceed her half-sister's displacement by roughly 400 tons. That four-percent growth suggests weak design control rather than harmless rounding. The ship had only two forward 12-inch guns, a top speed of about 14 knots, and a waterline belt reduced in height despite her tendency to sit lower than intended. After overseas and Mediterranean service, she was refitted as Rear Admiral Nikolai Nebogatov's flagship for the third Pacific squadron. Japan captured her at Tsushima and later sank her as a target, closing a career in which prestige repeatedly outran practical battle-line value.

Imperator Nikolai I grew heavier while losing protection
A design intended to be smaller than its half-sister became heavier, slower, and less well protected before serving as Nebogatov's flagship.
