I wouldn't use rockets on the fighter. We're still using wooden frame fighters, meaning that the backblast could easily catch the wings on fire.
Also, the structure of our rockets is probably quite similair to that of modern miniature rockets (Ie, a simple casing filled with gunpowder). Out of personnal experience, I can say that these have a tendency to fail when shaked to much. Especially when launched from a plane it's highly likely that the fuse'll come loose. (What kind of fuse do we use anyway, electric?). In optimal conditions, and with modern miniature rockets, at least 10% of the rockets fails to launch at the first attempt (Only 1 try on a plane), and 1-5% spontanously explode. With our rockets those percentage will be significantly higher. (Oh, and accuracy is pretty much limited to aiming up and away from your general direction)
Oh, and when a 50 kg rocket explodes at ignition, we loose the plane.
Last but not least, I highly doubt we'll be able to hit anything with them. The primary purpose of these early rockets is to function like some sort of mortar (Ie indirect fire). With a plane, that is unneeded, as we got both speed and altitude already. We just need to drop the bomb.
(( They're fine for it, they're light enough to carry and are a point and fire weapon for now, so useful against large targets like ships or against fortified position or for air support until we get something a bit more refined. Plus we'll be the only ones using them which gives us a nice morale shock weapon to hit the enemy with.
But we should build some of both so they are ready to go quickly and if we do it as two models we can then modify both in future to make them better as we get the tech. ))
Nah they're not. They are a mortar like weapon. (Basically, these primitive rockets are more self propelled mortar shells than real rockets). Highly inaccurate, and the payload is to low to penetrate heavy armor.
I'm not so sure about the morale shock from missiles, but I don't doubt that the plane whose wing just got torn of will make an impact.
You're thinking of missiles, not rockets.
