Rubin Central Design Bureau for Marine Engineering (Russian: Центральное конструкторское бюро "Рубин", romanized: Tsentralnoye konstruktorskoye byuro "Rubin"), abbreviated as TsKB "Rubin" (Russian: ЦКБ "Рубин"), located in Saint Petersburg, is the largest of Russia's three main centers of submarine design, the other two being Malakhit Marine Engineering Bureau and Lazurit Central Design Bureau ("Lazurit" is the Russian word for lazurite).

On January 4, 1901 the Marine Ministry of Russia assigned the task of designing a combat submarine for the Russian Navy to three officers: Lieutenant M.N.

The men submitted their design to the Marine Ministry on May 3, 1901; it was approved the following July, and the Baltic Shipyard was then awarded the order for construction of Torpedo Boat No.

It was this Construction Commission that after multiple transformations and name changes became the Rubin Central Design Bureau for Marine Engineering.

Construction of the Dolphin was completed in 1903, and its success in subsequent tests was the impetus for the creation of newer, more advanced types of submarines.

Bubnov, who had become Major General of the Naval Architect Corps and Honoured Professor at the Nikolayev Marine Academy.

Pustyntsev (ru:Пустынцев, Павел Петрович), who headed the Bureau from 1951 to 1974, created the design for Project 641 (NATO classification: Foxtrot), which began development in 1955.

The same year the Hotel-class submarine, which had begun development in 1956 as Project 658, was redesigned to enable underwater launching of D-4 ballistic missiles.

[4] Rubin now also works with outside companies (including Halliburton) on the production of oil platforms that are now[5] used in drilling around Sakhalin Island in the Sea of Okhotsk and in the waters adjacent to South Korea.

In 1999, shortly after the company was founded, the Sea Launch consortium claimed that their launch-related operating costs would be lower than a land-based equivalent due in part to reduced staff requirements.

Other recent projects include a high-speed train, the ES-250 Sokol,[9] intended for the Moscow-St. Petersburg Railway, and a design for a low-floor tram.
