Johns Hopkins Applied Physics Laboratory is partnering with the U.S. Navy to develop the AN/ALQ-249 Next Generation Jammer Mid-Band (NGJ-MB), designed to enhance jamming capabilities against enemy air defenses and communications.

Since the program's inception in 2001, APL has contributed expertise in solid-state amplifiers and phased array antennas, aiming to replace the outdated ALQ-99 Tactical Jamming System. Additionally, APL is involved in other Navy projects, including advancements in uncrewed surface vehicle autonomy and hybrid metal 3D printing for the USS Bataan.
