On photo one there is the ordinarry 57 mm Russian Air to Ground rocket and an other one with a different tail section and a bit shorter.
The tail has only six fins and are longer and can go more backwards while the normal tail has eight fins.
I have found little information in Jane's ammunition handbook 2006-2007 page 683 about a Ukrainian artillery system using the S-5M1 rocket with six fins.
I hope someone can verifing this and has documentation about the rocket.

Chris
