According to a pro-Moscow news site.
The Kremlin-supporting website Life reported that the cyberattack by hacker groups Killnet and Killmilk took place at 7 a.m. Monday.
“The notorious HIMARS multiple rocket launcher systems, supplied to Ukraine by the aforementioned military-industrial company, allow the criminal authorities of the kyiv regime to kill civilians, destroy Ukraine’s infrastructure and social facilities still temporarily occupied,” the hackers said in a statement reported by Life.
Hackers said Lockheed Martin “is the true sponsor of global terrorism, is responsible” for thousands of deaths. Newsweek finds no evidence that Lockheed Martin sponsors terrorism, or is involved in any form of terrorist activity.
A Russian military expert claimed on state television on July 28 that Russia had developed a “secret development” that allows it to hack into HIMARS systems.
On July 22, members of Killnet said, “We are using a new type of attack, we have no equal in this field. This is new technology that we are using for the first time against the world’s largest arms manufacturer, Lockheed Martin,” Life was reporting at the time.
According to a 2019 report by Business InternLockheed Martin specializes in everything from global defense to security to aerospace.
Newsweek has contacted Lockheed Martin for comment.
The HIMARS were supplied to Ukraine by the United States, and the weapons were touted as “a game changer” by senior Western military officials. The United States has promised Ukraine up to sixteen units, which can be mounted on a standard US Army M1140 truck chassis.
Each HIMARS can carry six GPS-guided missiles that can be reloaded in about a minute with a small crew consisting of just a driver, gunner and launcher section leader.
The range of the weapons is 80 km (50 miles), almost double the range of the M777 howitzers, another Western-made weapon that Ukraine has used against Russian forces since May.
A HIMARS can fire at ranges similar to conventional multiple launch rocket systems, at targets up to 300 km away.
On July 22, a senior US defense official said Ukraine had used HIMARS to destroy more than 100 “high-value” Russian targets in recent weeks.
Ukraine used the weapons to strike dozens of Russian ammunition depots, command and control sites and other targets such as critical bridges in the Kherson region.
Kyiv mounted a counter-offensive to retake the southern zone that fell into Russian hands in early March. Ukrainian forces have taken over dozens of villages and towns along the border and are pushing towards the eponymous regional capital of Kherson, the region’s military governor, Dymtro Butrii, said.
Russia is moving large numbers of troops to the region and other southern areas, Ukraine’s deputy intelligence chief said on Monday.
Kherson is strategically important in the conflict because it connects to the Crimean Peninsula, Ukrainian land that Russia annexed in 2014.
