Rather than raise the hangar and rearrange the after surface-to-air missile fit, the design gives the flight deck a movable section, pop-up roof, opening doors, and a mechanism that lowers the helicopter below deck level. The arrangement preserves the Kresta I profile even though Kresta II's raised stern created a different volume beneath the aircraft. The solution was ingenious, but it added weight, machinery, and failure points at the stern. A taller conventional hangar might have simplified aircraft handling and opened more usable volume, possibly including room for the absent towed-array sonar. The mechanism is a vivid example of innovation spent on preserving an inherited layout rather than reconsidering the whole after design.

The retractable Kresta II helicopter hangar
Kresta II's unusual retractable hangar preserves the existing stern and missile arrangement, but at the cost of an elaborate aircraft-handling mechanism.
