F-35 Shoots itself

isn't it bullet weight on target that counts ins ashort, ~ 0,5 second burst?

 

the BK27 (27mm)  and  or Defa/GIAT (30mm) guns have instantaneous max rate of fire while the gatling types invariably need to spool up their barrels. 

 

and anoher point, originally the F-35 was to have the BK27, so probably the B/C versions could have kept the internal gun.... instead of this strange podded version :devil:

 

 

Yes, sending more and/or heavier bullets in the same time is better. The spooling time is an issue but putting all numbers together the result is that the number of rounds from a gatling is roughly the same of the faster conventional guns  in short bursts.

Based on this, why go with a Gatling gun ? Because certain aspects of the Gatling guns make them preferrable in the US. Gatlings in particular are seen as more reliable and longer lasting compared to conventional gas operated types. Just mentioning a few, the barrels suffer from less wear as each barrel only has to shoot a fraction of the rounds compared to a single barrel gun. Gatlings are pretty immune to defective rounds and can shoot anything that fits the chamber while gas operated weapons are more sensitive to ammunition. Gatlings dissipate heat quicker, again because of the multi-barrel approach, so leading to less risk of malfunctions....

Now this may all sound academic, afterall there have been plenty of conventional guns with good performance and reliability and in Europe we historically tend to prefer gas operated weapons, but it's a fact that in the US the features of the Gatlings make them the preferred choice

Just saw this and haven't seen anything else on it. An F-35 flown by the Marines fired its Gun in support/training, and caused $2.5 million in damage. Its being listed as class “A” damage. Which is catastrophic or write off according to the article.

The class of damage is determined by the dollar amount to repair, unless the aircraft is a total write off (except for RPAs) or there is a loss of life or permanent disability involved, then it's automatically a Class A.  LINK

Considering the very little time in which an enemy aircraft is in the sight, it's not much the first few bullets that count, what matters is to be able to lay down enough bullets to have a decent chance of hitting. Reason why rate of fire is one of the most important aspect in an aircraft gun.

 

 

This.  Given the inaccuracies of a moving object trying to hit another moving object with a moving object, more is better.  The amount of computation that goes into calculating a gun solution in an aircraft is staggering, and one of the big advances made in recent generations of gunsight is less assumption of parameters and more use of the actual parameters of both the shooter and target to calculate the firing solution.

60k-600k is remarkably not a lot of damage (at least at the lower end)!

Considering a new set of manuals costs about $15k, this is pretty good value damage 😉
