Capt. Al Lamb (pilot) and Capt. Jack Donovan (electronic warfare officer), flying in a North American F-100F Super Sabre modified for the Wild Weasel radar suppression mission, knock out a North Vietnamese Fan-Song radar at the Yen Bai rail yards north of Hanoi, while the F-105 crews they were escorting destroy the nearby SA-2 SAM site. This attack marked the first success for the Wild Weasel program. Lamb and Donovan were each awarded the Distinguished Flying Cross for the mission.
The Pentagon awarded a $2.02 billion contract for Lot 17 of F-35 engines to contractor Pratt & Whitney on June 5. Work on the F135 engine is expected to be completed by December 2025.
