Lightweight . . . easy to install and integrate . . . adaptable to a wide range of electro-optical sensors . . . and mission reconfigurable . . . the LSEOS is an exceptionally versatile and functional system.

Rapid Surface or Air on Target Response

To rapidly and effectively counter today's emerging littoral threats the LSEOS is designed to provide:

  • The highest performance sensor suite

  • Exceptional manual and automatic target tracking

  • Complete short and long range surveillance

  • Maximized line of sight stabilization

Exceptional for New and Retrofit Vessels

LSEOS is used for fire control as well as surveillance, covert tracking, and damage assessment. Two platforms of the LSEOS product line can be used on vessels as small as patrol boats to the larger frigates.

Today, more than 50 ships and 4 navies are benefiting from the technology and adaptability of L-3 Brashear's electro-optics. L-3 Brashear electro-optics are also used in conjunction with radar/sonar systems. For example, the LSEOS MKIV is part of the U.S. Navy Phalanx Block 1B CIWS Upgrade where over 40 ships to date have been upgraded.
