An operation by Ukraine’s Security Service (SBU) has hit “more than 40” Russian bombers at air bases “in the rear of the Russian Federation,” a source in the agency told the Kyiv Independent on June 1.
“Enemy strategic bombers are burning en masse in Russia — this is the result of a special operation by the SBU,” the source said.
Video provided by the source shows what appears to be a row of heavy bomber aircraft on fire at an undisclosed location.
Fissile material (enriched uranium and plutonium) has a long half-life.
AFAIK tritium is the biggest issue, with a half life of 12.3 years. From what I’ve read, nukes have little feeder tubes to replenish that.
