L-3 KEO’s <strong>MK46</strong> <strong>MOD</strong> 1 has significant expansion capability to incorporate emergent<br />

technologies.<br />

DESCRIPTION<br />

L-3 KEO’s <strong>MK46</strong> <strong>MOD</strong> 1 <strong>Optical</strong> Sight System<br />

(OSS) is a fully qualified OSS for major surface<br />

combatants and is MIL-S-901 grade A shock<br />

tested. Our <strong>MK46</strong> <strong>MOD</strong> 1 is installed on all<br />

U.S. Navy Arleigh Burke-class destroyers.<br />

The modular design allows the system to be<br />

configured or upgraded to provide for special<br />

missions and to maintain the system as current<br />

state-of-art. The U.S. Navy and L-3 KEO began<br />

a series of upgrades to provide the operators<br />

with more capability, including a new eyesafe<br />

laser rangefinder, a new 3 to 5 micron thermal<br />

imaging camera, a color television camera, and<br />

utilization of the standard UYQ-70 console.<br />

Other improvements include an upgraded<br />

azimuth motor, new automatic tracker, and the<br />

addition to automatic modes of operation. The<br />

<strong>MK46</strong> <strong>MOD</strong> 0 and now the <strong>MK46</strong> <strong>MOD</strong> 1 are<br />

operational and have proven their utility to the<br />

U.S. Navy.<br />
