5 Hryven First launch of rocket Zenit-3SL

The Zenit-3SL was the launch vehicle at the heart of Sea Launch, a multinational commercial space venture that used a converted oil platform in the Pacific Ocean as its launch site. Ukraine's Yuzhnoye Design Bureau and Yuzhmash factory in Dnipro built the Zenit rocket itself, while Boeing, RSC Energia, and Aker Kvaerner held the other consortium stakes. The first successful commercial launch from the Odyssey platform occurred in October 1999.

Sea Launch filed for bankruptcy in 2009 before being restructured under Russian majority ownership — a geopolitical complication that effectively ended Ukraine's active role in the program well before this coin was issued.
