But unlike rocket pod, the singular rocket has a changeable burn timer and weight, through which you can affect it's ballistics. Also, you can use it as a rudimentary mean of propulsion that has an unchangeable thrust of 500kgf per rocket, can't be turned off until burnout, smokes until destruction, but is independent from air and fuel tanks, and also has instant response(that was handy before introduction of ThrottleResponse to jets). For example, the BogdanX used them as droppable take-off boosters in his Tu-14. I used them as starting boosters for Brimstone ATGMs in my Tempest.
(Damn, the mighty BogdanX got deleted with all his planes, WTF!?)

so that makes rockets obsolete, since you can have 7 of them at once, aight got my answer:
rocket=bad
rocket pod=good

The fin option relates to a visual change, its purely visual
Rockets are unguided thus they cant home onto a target
Missiles are guided
@ThatOnePiaz

@Bryan5 got it

@ThatOnePiaz also, use the "Reply" button when replying to someone, so they receive the notification

@ThatOnePiaz no

no homing or anything?
because it has the fin option
which rocket pod lacks

rocket pods are just the regular rockets but in a pod
