Yep 143/143A based on the Lurssen FPB-57 are wood but the newer 148 is steel. The follow-on Type 148s are based on the French La Combattante II, which like Combattante IIa and III are steel hulled.Albatros/Gepard -> wood
Komar -> wood
PT -> wood
almost all MTB -> wood
Numbers over the past 100 years heavily favour wood. Steel in bignumbers was used on e.g. the Osa and Hegu classes. A couple classes of 4-8 ships have no impact on the overall numbers really.
In modern ships of this role, steel has less than a 50% market share.
(wooden) Komar > replaced in productions by (steel) OSA
(wooden) PT > WWII era ships, built from wood in part due to steel shortages.
(wooden) MTB > WWII era ships, see above
We're not talking about the past 100 years but about what's in used or on the market today. Like it of not, most FACs of today are no longer wooden. I did also mention aluminium (alloy) and plastic. If you have market data, do please post.
