Hello,

On the AVSIM forums Dominik Mann asked the following question but so far no-one has answered it. Having seen the question I am now curious about the same thing!

He asks: "What do those abbreviations after the plane type designation actually mean?

For example, let's take the Su-15TM. What "Su-15" means is pretty obvious, but what does the "TM" mean?

I gather it is an abbreviation for something, but since I do not speak Russian I have no idea what it could denote."

If anyone here could answer his question then I will let him know.  

Спасибо,

Iain Spowart,
