Why Russia is suddenly building giant shelters for bombers that once sat in the open

 In a significant departure from Cold War practices, Russia is now building extensive protective shelters at Engels Air Base for its strategic bombers. This initiative is a direct response to recent drone attacks that exposed vulnerabilities within their airbase operations. With an aging fleet of bombers, Russia is focusing on ground survivability to ensure its strategic deterrent capabilities remain effective in contemporary conflict. In a significant departure from Cold War practices, Russia is now building extensive protective shelters at Engels Air Base for its strategic bombers.
