Exocet armed Combattante IIa and IIIa
The IIa is basically one and the same as the German Type 148 Tiger, Libyan
Beir Grassa and Iranian Kaman/ Sina classes. The Israeli Sa'ar differ in armament.
5 went to Chile and Egypt, each. One, Dioscuria (former P17 Ypoploiarchos Batsis, former HS Kalypso) was tansferred to the Georgian navy and was subsequently sunk by the Russians in 2008.
Important to note that the 4 original Exocet armed Combattante II's for Greece substituted the front main gun for a second twin 35mm AA cannon. These (P14 Anninos, Konidis, P15 Arliotis and P17 Batsis) were built by CMN Cherburg for Greece and served between 1972 and 2002.
The ex-German IIa's Votsis (P 72), Pezopoulos (P 73), Vlachavas Ρ-74, Tournas (P 76) and Sakipis (P 77) were delivered between 1994-1995 and are still in service.
Malaysia also uses four Combattante IIs (Perdana class)
Of the German built TNC45, exocet armed equivalent, two were bought by Argentina (1974, Interpida class) four by Bahrain (1984, Al Fateh class) six by Kuwait, all captured by Iraq and subsequently sunk during the Gulf war of 1990, except one that was returned to the emirate.
The six 1968 built Singaporean Sea Wolf class boats carried the Sa'ar 3/4 Harpoon/Gabriel armament mix instead. The Singaporean boats were withdrawn ten years ago.
The 4 enlarged Combattante IIIa 's were built in Cherburg and delivered by 1976-1977 and, upgraded, are still in service. These are P20 Laskos, P21 Blessas, P22 Mykonios and P23 Troupakis. They are FACs of corvette size.
Qatar (three, Damsah class) and Tunisia (three, Gali class) use IIIa Combattantes as well.
@Patine Παντελονόψαρα, not whales

I just found out that Spain, Colombia (Lazaga class patrol boats, all decomissioned), Morocco (four Al Khattabi class, MM40 armed) and Kuwait (two Al Instiqlal class, one sunk by Iraq) also used/ use variations of the same design. Another three were ordered by Lebanon this year (of the updated FS56 class)
