- Ukraine reportedly killed two top Russian pilots using US-donated HIMARS.
- The father of one of the pilots made the revelation to Russian media.
- The US has sent Ukraine 12 units so far, with another four on the way.
Two top Russian pilots were killed by HIMARS, a long-range rocket system supplied by the US, a report says.
Lieutenant Colonel Maksim Potyomin, 41, died in Donetsk on July 8 when his motorcade was hit by precision-guided rocket artillery, the MailOnline reported.
Another fighter pilot, Colonel Anatoly Stasyukevich, 54, is also believed to have died in the same attack.
While the news of their deaths was previously known, Maksim Potyomin's father Alexey told Russian outlet V1.ru this week that he believed his son's death was caused by a HIMARS strike.
"As far as I know, the car with my son was hit by a missile from the HIMARS complex, which we have been hearing so much about lately… The resulting injuries were incompatible with life," Potyomin told the outlet.
The pilot's funeral took place on Sunday, where he was buried with full military honors, the outlet reported.
Both pilots were senior officers in the 1st Guards Baranovichi Red Banner mixed aviation division, said the Mail Online. It was the first unit to receive the Sukhoi Su-57 fifth-generation fighters in 2019 and includes a helicopter-rescue detachment, according to reports.
The High Mobility Artillery Rocket Systems (HIMARS), which first arrived in Ukraine last month, has begun to play a crucial role in the fight against Russia.
The US has given Ukraine 12 units so far, with another four on the way, according to Gen. Mark Milley.
A military expert told Insider's Sinéad Baker that HIMARS is the "perfect" weapon due to poor Russian logistics forcing senior commanders into its range.
HIMARS are more advanced than Ukraine's existing artillery capabilities and can hit targets as far as 50 miles away.
Ukraine said it had used the weapons to kill a Russian general, destroy 50 ammunition depots and strike a key bridge.
Russia reacted angrily to the US sending Ukraine the weapons, with Russian President Vladimir Putin threatening to escalate his bombing campaign in response.
The two fighter pilots are among the latest of dozens of senior Russian officers to be killed in Ukraine.
