The US Army is looking at developing two new surface-to-air missiles aimed at reducing the cost-per-kill against airborne threats that are less than state-of-the-art (e.g. non-stealthy, low-ECM). These would include cruise missiles, fixed-wing aircraft, helicopters, and UAVs.
The LCI is a 10-inch diameter missile designed to be launched from a Patriot TEL (probably replacing a PAC-3), with a range of up to 90+ miles and a cost of around $100k each.
The MERLIN is a two-stage 7-inch diameter missile that uses LCI technology, and is launched from a SLAMRAAM HMMWV launcher, with up to a 25 mile range and a similar low-cost.
I can't find anything on the proposed guidance other than they were looking at LADAR and GPS/Inertial systems for the LCI.
The idea would be to save SLAMRAAMs and PAC-3s for the hard targets, and use MERLIN and LCI for the easier ones.
