The Neutron Beam is a gun-type weapon appearing in Ace Combat 3: Electrosphere. This particular weapon is the result of Neucom Incorporated research on space technology. Being an energy-based weapon, the Neutron Beam does not suffer the problems of standard aircraft ordnance caused by space vacuum. The energy fired by this weapon is composed of super-heated neutrons found in atoms—it is the neutrons' high temperature that caused damage, instead of kinetic energy.
Ace Combat 3: Electrosphere
The weapon makes its only appearance in the mission Zero Gravity, in both the NTSC-J and export versions. It is the only machine gun-type weapon of the R-352 Sepia, the spaceship flown in this mission.
- Despite being exclusive to the R-352, the Neutron Beam is the second fastest firing gun weapon in the entire game. The Laser Cannon has the longest range and strongest damage rating, but fires very slowly.
