MOSCOW, FEB. 8 -- Soviet President Mikhail Gorbachev today named Leonid Kravchenko, accused by liberals of reviving censorship in his current post as state radio and television chief, to lead a powerful new broadcasting company.

A presidential decree announcing formation of the company said it would assume the functions and funding of Gosteleradio, which was effectively a ministry of radio and television and nominally subordinate to parliament.

Many television journalists say Kravchenko, a member of the Communist Party Central Committee and former head of the official Tass news agency, has restored strict political supervision.

Meanwhile, KGB Chairman Vladimir Kryuchkov disclosed a shakeup in the top ranks of the security police, in which two generals in their sixties were replaced by younger men.

Kryuchkov told the government newspaper Izvestia that Gen. Filipp Bobkov, until recently the second most powerful man in the KGB, resigned last year. Bobkov, 66, served in the KGB for 45 years and was in charge of the Fifth Directorate, responsible for ideology, in the late 1970s and early 1980s under then-Soviet leader Leonid Brezhnev. The Fifth Directorate, now disbanded, was much criticized for its aggressive pursuit of dissidents.

Kryuchkov said his new first deputy was Viktor Grushko, who had headed Soviet counterintelligence for about a year, the newspaper reported.

Lt. Gen. Gennady Titov, a career intelligence officer who headed KGB operations in the former East Germany, was given Grushko's job, Kryuchkov said.

Another KGB deputy chairman, Vladimir Pirozhkov, 66, resigned after more than 20 years' service and will head the veterans' movement in the security police.

"The leadership of the KGB has taken quite an unusual step, appointing extremely young men to important posts," Izvestia said. It did not say how old Grushko and Titov are.

Kryuchkov said Valery Vorotnikov, 45, now heads the Directorate for Defense of the Constitution, which replaced the Fifth Directorate.
