The moonbase interceptors proved more effective than anticipated, but losses were also greater, so after 2 years of operations a review was carried out in an effort to improve the design. Modifications that were recommended were:
Retractable landing gear (one interceptor lost after a skid, damaged by space debris, collapsed on landing)
Laser pods as secondary weapons (two interceptors lost to enemy fire after using their missiles)
Backup solar power source. to power life support and thrusters (one astronaut lost after his ship lost power while on a vector away from earth)
Replacement of bubble canopy with smaller slit window used on Moonhoppers, as heat and radiation management proved to be a problem.
An extra crew member, as the workload was considered too great for a single pilot, even with moon base controllers.
Additionally the unguided missiles were replaced with a cruise-missile derived design that allowed the weapons operator to alter it’s course in flight, as the target manoeuvred to avoid interception. The warhead was also modified so the ball bearings were expelled in a 70 degree cone forwards of the missile only, after one interceptor and several satellites were destroyed by stray shrapnel.
The new interceptors entered service in mid 1984, and this time the Orbital Weapons Launcher appellation stuck, and they became known as OWLs. The Owl was hugely popular with its crews and much more effective than the Mk.1, the combination of weapons allowing the interceptors to corral the UFOs using the guidable missiles and close to dogfighting range with laser cannons to finish off any that escaped.
Here is my OWL, modified from the Bandai interceptor I made when I was a kid, and somehow managed to survive. Note the Angry Owl squadron markings!
