For the first time in recent history, Ukraine conducted burn tests of the Cyclone-4 class launch vehicle, Pivdenne Design Office reported.
"On August 23, on the eve of the 28th anniversary of our country's independence, for the first time in its recent history, burb tests of the launch vehicle stage as a whole were carried out. It's the third stage of the Cyclone-4 middle-class launch vehicle designed by Pivdenne and manufactured at Yuzhmash," the report says.
It is noted that these are the final and most important tests before the first flight tests of the third stage of the Cyclone-4 launch vehicle, which will work directly in space, bringing satellites to the target point.
"During the fire tests of all systems worked perfectly, the stage engine was turned on five times, as planned by Pivdenne designers. The tests were recognized successful!" the design office said in a statement, adding that a detailed report is yet to be published.
