The Peruvian Navy has earmarked $ 4.7 million to purchase two sets of decoys Softkill Multi Ammunition System (MASS) for installation in two class frigates Aguirre (Lupo) to be supplied by Rheinmetall. The Navy intends to upgrade four remaining vessels, but is short of sufficient funds.
The other ships would have limited improvements for enhanced performance in certain areas. At the heart of the program is the new combat system Varayoc control, which was developed by the Services Industrial Marina (SIMA) and has been installed in the BAP Carvajal.
Now, the Army has begun to replace obsolete combat system Alenia IPN-10 by Varayoc aboard two frigates, continuing later with the other ship.
