Russian Army Adopts New Training System.

Four new 16Yu6T unified training systems for the S-400 Triumf (SA-21 'Growler') and S-300PM2 Favorit (SA-20 'Gargoyle') air-defence missile systems have been accepted into service by the Russian armed forces. These will replace the earlier Altek-300 training system.

Also known as the Unifitsirovanniy Trenazhniy Kompleks (UTK), the 16Yu6T was developed by Golovnoye Sistemnoye Konstruktorskoye Byuro Almaz-Antey (GSKB Almaz-Antey), working under the Tenor-PVO experimental-design programme.

Although a prototype of the new training system was completed in 2010, a contract for the production and delivery of the 16Yu6T was not issued by the Russian Ministry of Defence until December 2013. 

This delay created problems for the company, given the rapid pace at which new electronic components are developed, and existing devices become obsolescent and are phased out of production.
