Two Belgian Air Force staff on the ground had to be treated for injuries after the accident.
The incident took place at Florennes Air Base last Thursday, with two servicemen who triggered the gun suffering from hearing damage.
Base commander, Colonel Didier Polome said: “You can’t help thinking of what a disaster this could have been”.
Firefighters were brought in to tackle the blaze at the airbase.
The Belgium Ministry of Defence have launched an investigation into what exactly happened.
The Dutch aviation magazine, Scramble, have even shared pictures of the burned out aircraft.
The magazine have said that the aircraft had just been refuelled and prepared together with another F16 and after being hit by the bullets, exploded instantly.
The Belgian air force now has 54 F-16s remaining.
The military airfield is two miles southeast of Florennes, a Walloon municipality of southern Belgium.
It is home to the 2nd Tactical Wing, operating F-16 Fighter Falcons.
Until July 2009, the airbase was also home to the Tactical Leadership Programme, a joint training programme established by 10 NATO members.
Writing for the Aviation24 website, Commander of Florennes Air Base, Mr Polome, defended the technicians: “In our own country where these people work every day to prepare aircraft for their national missions such as securing our airspace.
“To name just a few. They do not complain, and we agree that this is inherent in the military life they have chosen.
“All are highly motivated and give the best of themselves every day, in circumstances that are not always ideal in terms of infrastructure, available equipment or the number of colleagues.
“Performing these successful missions requires ongoing training of our personnel, as well as constant maintenance and modification of the aircraft to keep them operational.
“It is an endeavour made up of successive human actions and people are, one day, fallible.”
