A hybrid version of the JDAM family that combines GPS/INS guidance with a laser seeker in the nose.
LJDAMs are designed to hit moving or last-second-updated targets, keeping the all-weather benefits of JDAM while adding terminal laser homing.
Key characteristics:
- Dual-mode guidance:
- Midcourse: GPS/INS guides the bomb along a programmed path toward the target area.
- Terminal: A laser seeker homes in on reflected laser energy in the final seconds before impact.
- Midcourse: GPS/INS guides the bomb along a programmed path toward the target area.
- Moving targets:
Unlike standard JDAM (fixed coordinates only), LJDAM can adjust its impact point during terminal guidance to follow a lased moving target (vehicles, boats, etc.). - Flexibility:
- Can be employed as a pure GPS/INS weapon if no laser designation is available.
- Can refine accuracy or shift aim point with a laser even if coordinates were approximate.
- Can be employed as a pure GPS/INS weapon if no laser designation is available.
- Employment sources:
The laser energy can be provided by:
- The launching aircraft (self-lase with targeting pod),
- A wingman (“buddy lase”), or
- A JTAC/AFAC on the ground or in the air.
- The launching aircraft (self-lase with targeting pod),
- Typical variants:
Built by adding a laser seeker kit to standard JDAM bodies (e.g., GBU-54 as the 500 lb Laser JDAM).
Application in DCS World
- Current status:
DCS does not currently model LJDAM as a distinct, fully dual-mode weapon in the core modules. Players generally employ:
- JDAMs as pure GPS/INS PGMs, and
- LGBs (GBU-10/12/16) as pure laser-guided bombs for moving targets.
- JDAMs as pure GPS/INS PGMs, and
- Conceptual use:
Even without a dedicated LJDAM in DCS, understanding the concept helps cadets grasp why real-world forces mix JDAM and LGB roles, and why some modern weapons blur the line between coordinate weapons and terminally guided weapons.
Training guidance for cadets
- Treat LJDAM as the bridge concept between JDAM and LGB:
- JDAM = all-weather, fixed coordinates.
- LGB = requires continuous laser, great for movers.
- LJDAM = JDAM with the ability to refine/hit movers via laser in the terminal phase.
- JDAM = all-weather, fixed coordinates.
- In DCS practice, you can simulate the tactical thinking behind LJDAM by:
- Using JDAM when you have accurate coordinates and weather is bad.
- Using LGBs when attacking movers, or when a JTAC/AFAC is providing laser designation.
- Planning strikes as if you had LJDAM: fixed coordinate to get you close, then terminal laser for precision and movers (even if the sim uses an LGB in that last step).
- Using JDAM when you have accurate coordinates and weather is bad.
This gives cadets the correct mental model for modern weapons, so when/if true LJDAM-type weapons appear in DCS, the doctrinal understanding is already in place.
