Even if the Damage Method remains the same (Penetrator as per the missile, then HE warhead of 160 to 165kg), with a Terminal Guidance Radar (about 6km to 10km from target from what i’ve seen // can be different depending on models/standards)
You must take care of the specifics variants:
→ MM-38 // MM-40 stands for Mer-Mer (“Sea-Sea” for english speakers), so “from ships to ships” Warfare (also been modified for Coastal batteries - Still MM40 but in Ground-Sea mode)
A- the 1974- - MM-38 is the earliest model of the missile
Range 40km
the only missile to have been discontinued from production today.
B- MM-40 is the latest Exocet model, with various standards
MM40 B1 - 1981 - Range 70km
MM40 B2 - 1992 - Range 72km
MM40 B3 - 2010 - Range 180+km (can go 180° to avoid Interception missile)
MM40 B3C - 2023 - Range around 200km
(others improvements)
→ SM39 / SM40 stands for Sous-Mer (“Sub-Sea” for our english friends), is a specific variant made for Submarines Warfare and Tactics
Several Standards appears:
SM39 B1 - 1985 - Range of 50km
SM39 B2 Mod2 - 2009 - Range of 60-70km (in good Sea conditions?)
(others improvements)
a breaking “new born” : the SM40 is an adapted MM40 B3C missile unveiled at Euronaval 2024
MBDA Estimated the Range to 120km for this variant
All SM39/SM40 are shortenned variant of MM40’s in order to enter the 21" torpedo tubes in use of French Subs, explainning the Shortenned Range.
→ AM38/AM39 stands for Air-Mer (“Air-Sea” for our english friends), is a specific variant made for Aerial Warfare and Tactics
the 1977 “Unknown” AM38 (based on MM38) - 5 produced, all fired from SA 321 “Super Frelon” Helicopters without live charges
The Standard:
AM39 B1 - 1979 - Range of 50-70km (depending on aircraft parameters at Launch)
