Kimon-class (FDI HN) frigate evolution from Standard 1 to Standard 2++ configuration
Standard 1 → MN/FR configuration with the addition of a LWS/L-ESM (Saab NLWS), WiMAX/5G, S-100 CAMCOPTER UAS, 76mm MFD, and LIONFISH 20 RWS instead of NARWHAL, along with other configuration differences.
Standard 2 → Addition of two A50 SYLVER VLS modules, AAW DLS (four SYLENA Mk1 launchers), 21-cell RAM launcher.
Standard 2+/2++ → Major software and system upgrades to the SETIS CMS, asymmetric warfare center, sensors (including PASEO and SENTINEL), and other electronic systems, together with full integration of the S-100 CAMCOPTER UAS and enhanced weapon-system integration, including RAM Block 2B/C and 76mm special ammunition.
Standard 2+++ (potential) → Replacement of one A50 SYLVER VLS module with an A70 SYLVER module (potentially SYLVER NG) to accommodate NCM.
Other installations: CENTAUR C-UAS
Potential: R-ECM
