There are numerous instances, but don't have time time to really go through and verify all of them. I have my Mac 7 Dynamite DVD and just watching and going to the battle scenes and found one instance.
Mac 7 Dynamite Episode1: 22min:20-30sec
The Zolan Patrol launches in their VF-5000s towards the galactic whales and one of the patrol members laments that they don't have enough "valkyries" to protect the whales against the poachers.
Anyway, as for the the "wierd" pronunciation, its actually quite common for the japanese to pronounce it in more syllables than english speakers do. Example: native english speakers pronounce "macross" as "MA-CROSS" and Japanese will pronounce it closer to "MAr-KOO-LOWS"
