Listen-Kill Missile

Listen-Kill (aka L-K or LK) missile technology is an upgrade to missiles (both LRM and SRM) to improve their accuracy. This is achieved through a small computer and homing device in the missile's head that allows it to home in on the electronic noise of a BattleMech or tank. Although very successful at first, the effect L-K technology was quickly negated by jamming equipment tailored to counter it.

Although L-K missiles are generally considered to have been introduced only in 3038 by the Federated Commonwealth, prototypes were used as early as April 3029 by the Kell Hounds, then the in employ of the Lyran Commonwealth, in the defense of their base on Lyons. The first large-scale deployment of L-K missiles was during the War of 3039, but L-K missiles were still prohibitively expensive and used sparingly. It was not until 3042 that the New Avalon Institute of Science found a way to mass-produce L-K missiles.

Following their use in the War of 3039, the Draconis Combine was quick to develop a plug-in ECM module that was distributed to their line units starting summer 3039 and totally countered the effect of L-K missiles. They also reverse-engineered the L-K technology and had it available for themselves from July 3039 onwards. AFFS and LCAF were thus forced to also develop ECM technology, which they had available by 3040.

By the mid-3040s, L-K missiles were common, but almost all units in the Inner Sphere were equipped with ECM gear to negate their effect. Since L-K missiles are still more expensive but have lost their advantage, it is largely a moot technology afterwards (except perhaps against very old 'Mechs without ECM refit).

Rules

• L-K missiles can be loaded on any LRM or SRM launcher
• When firing L-K missiles, the launcher has -1 to-hit bonus against any non-Clan units without ECM upgrade
• L-K technology cannot be combined with any other type of missile submunition (such as Inferno, Artemis, NARC, Thunder-LRM, etc.)
