Gunfire Test of the U.S. Navy’s

Improved Kinetic Energy –

Electronic Time Projectile


The Navy’s 5” 54 and 62

Caliber Guns

"History does not long entrust the care of freedom

to the weak or the timid" – General Eisenhower

Cruisers (CG’s) Destroyers (DDG’s)


Navy’s Requirement

The Navy’s 5” 54/62 caliber guns have an anti-

surface warfare requirement to defend against

small boat threats

• Swarming tactics

• Terrorists

• Pirates


• The MK 182 KE-ET is currently fielded in the fleet

• KE-ET: The pellets lose kinetic energy by being expelled

from the base

• IKE-ET: The pellets gain kinetic energy by being expelled

from the nose

IKE-ET vs. Stop Sign


• The IKE-ET is still in the Small Business and

Innovative Research (SBIR) phase

• What’s to come? • Currently the contractor is redesigning the projectile

specifically for this application

• After the redesign phase we will test fire the projectile

again to verify survivability and functionality

• The test will also attempt to acquire dispersion and

velocity data (Z-data)

• The Z-data will be provided to the lethality analysts to

characterize IKE-ET’s effectiveness vs. certain targets

• The lethality results will support a decision whether or

not to proceed with the program

The Future

of IKE-ET
