FS2002/FS2004 Sukhoi Su-25K/TM (Su-39) Frogfoot. The Su-25 is an aircraft developed based on almost the same specification as A-10 of the U.S. Air Force. A very orthodox form by the bimotored engine of low output is adopted. However, almost all of the development demands of low-cost and easy productivity and high survivability by heavy armor and a strong ground offensive capability etc. are achieved. Many Su-25's were granted to the friendly countries of the old Soviet Union. About 240 are still present to Russia. The newest model is Su-25TM (Su-39) with strengthened electronic equipment. Four kinds of airframes and four kinds of painting examples are included in this file. By Kazunori Ito.
