The LAU-88/A Triple-Rail Missile Launcher was manufactured by Hughes for use with the AGM-65 Maverick.
However, the F-4 Phantom only carried two on each launcher - inboard and lower stations.
I found almost no information about the launcher, so I'm sure it has serious shortcomings.
The Maverick is modeled on photographs and information taken from the internet.
It is not a model based on engineering information, but a personal interpretation with many details assumed.
