Canada purchased 98 single-seat CF-18A aircraft, and 40 dual-seat CF-18B aircraft. We lost 18 aircraft due to accidents, no combat losses. Currently we have 72 CF-18As and 31 CF-18Bs in inventory, of which 79 are in operational use. Doing the math, that leaves 17 aircraft that have been written off. The Pravda article says 20. According to Wikipedia...

19 June 2004: Aircraft from CFB Cold Lake lost when it skidded off the runway during landing at Yellowknife, Northwest Territories. Aircraft was salvaged and is back in service. Pilot ejected but was injured.
But that aircraft is back in service, so not one of the 18 lost. So first of all, 17 were written off, not 20. And the aircraft written off have been scavenged for parts, so don't expect they'll ever fly again. I wish they could be repaired, upgraded, and put back in inventory; but have no idea what that would take. They've been used as a source of spare parts so long that I expect they all are sad relics that can't fly.
