Australia's Oliver Hazard Perry Frigate Upgrade
All new electronics systems will be added to allow the weapons upgrades and additions. The ships’ existing Mk13 GMLS pop-up launcher will retain its 40 round magazine, but will be fitted for more advanced SM-2 anti-air missiles and Harpoon strike missiles (usually fitted 32 SM-2 and 8 Harpoon). An 8-cell Mk41 tactical-length (vs. longer strike length) vertical launching system adds room for another 8 SM-2 Standards – or up to 32 shorter-range RIM-162 Evolved Sea Sparrow air defense missiles.
Self-contained drop-in weapon changes round out the mix. The ship’s 20mm Phalanx CIWS last-ditch defense systems will be upgraded to Block 1B for better capabilities against UAVs, helicopters, and small boats; the MU90 Eurotorp lightweight torpedo will be ready in the torpedo tubes; the Harpoon anti-ship missiles will be RGM-84 Block IIs with GPS guidance and land attack capability; and RAFAEL’s Mini-Typhoon 12.7mm remote weapons systems will supplement the Phalanx’s defenses against fast boats and similar threats.
