The IULLDES - Intergrated Ultra-Low-Level DEfence System - is designed to destroy incoming sea-skimming missiles. It uses the following components:
SA-N-20 SAM system
*Variant of SBI-16 Phased-Array radar system, for long-range targeting of sea-skimming missiles, with inbuilt ECCM capability and frequency-agility, designed to counter jamming-equipped missiles; radar guidance backed up by Imaging Infra-Red Guidance and short-range (30Km) LADAR units mounted on ship's deck or superstructure in armoured casings, also millimetric-wave X-band radar; when inbound missile is detected, all guidance systems are activated, so that even if missile approaching behind jamming and/or from sun missiles are still guidable;
*SA-N-20 SAM, short-to-mid-range sea-skimming-capable missile with inbuilt active radar guidance; around central radar is a ring of small, short-range laser emitters, allowing guidance even in heavy jamming environment; lasers have narrow beam and high power allowing acquisition of targets even in bad weather; missile also carries tertiary backup IR guidance module alongside radar unit; missile can be guided by internal systems or by encrypted digital command relay from targeting ship/s; missile computer will follow information from both ship guidance modules and self-contained guidance modules, depending on which is decided as being more likely to be the inbound missile.
*Falanga CIWS-II, short-range superheated tungsten-carbide/DU flechette launcher. Launches flechettes in approximately circular pattern, with "cone" at core, along predicted track of missile; much larger kill radius than conventional CIWS (approximately 3m when conducted against samples of Yakhont-3 AShM); triple-unit flechette launchers also allow high rate of fire (approx. 200 flechette bursts/minute) to be attained. Launchers guided by radar/ladar unit mounted above each launcher and/or main shipboard radar/ladar units. Flechettes have extremely high velocity and very high rate of fire, capable of kills to ranges of 150-170m. Secondary launcher launches flechettes in a tight rectangle pattern. Flechettes are superheated by high-power electric filaments within the launcher units, and kept heated (though not at so high a temperature) by similar units within their magazines belowdecks; magazines have 30mm composite armour and fire-suppression systems. Flechette filaments in launchers must be replaced after 40 hours' use; improved filaments under development.
Costs: Approx. 1.5 million for 1 installation of 2 SA-N-20 launchers, 2 guidance units and 4 Falanga CIWS.
