Enhanced Laser Guided Training Round / ELGTR

Also known as
  • ELGTR
  • Enhanced Laser Guided Training Round
  • BDU-59B/B

The Enhanced Laser Guided Training Round (ELGTR), sold as BDU-59B/B, is Lockheed Martin's U.S.-made live-fire Paveway II training round. Official product material says it has been deployed since 1992, gives aircrew and terminal air controllers realistic GBU-10/12/16 practice, and is a cost-saving alternative to expending tactical laser-guided bombs.

Paveway II Training Relationship

Lockheed Martin describes ELGTR as a live-fire trainer for Paveway II GBU-10, GBU-12, and GBU-16 employment rather than as an operational bomb.
