Sorry you are right... Penguin ASM comes from Norway, got it
mixed up when I was typing this 
Oh, sources, Flight Internation, Year sometime in the late 80s,
early 90s. I don't have the hard copy anymore. It was at the time
when RSAF just got their A/B Vipers. TNI also got or just about to
get their Vipers. RMAF was interested to acquire them later for
their MPAs.
Sadly, I remembered this but I don't have anymore hard copy for
reference. Perhaps a quick search on the internet may yield
something.
Anyway, RSAF got the -G version of Maverick in their 94 Viper
package. The G version is specially effective against seaborne
targets as they too employ an IIR seeker, longer enduance rocket
motor, and an enlarged warhead.
