Veritably false. Jets have far greater kill chain completion times and poorer OODA loop management.
Phase
Fixed Wing
Rotary
Find
Radar / EOTS / TGP / IRST
Radar unreliable with detection because ARMA 3 and really good reasons. Soda straw aperture flying over a small area at high speed without any thermal imaging.
Radar / EOTS /IRST
Wide FOV, gunner can simultaneously look through a thermal imager and refer to radar screen.
Fix
Painfully cycle with assigned key while trying to actually fly the jet whilst attempting to avoid possible AA fire.
Gunner selects target, pilot hovers comfortably (division of labor is fantastic isn't it).
Track
Correlating position on subsequent passes until strike authorized, an annoying matter itself w/o TrackIR and all jets notwithstanding the F/A-181 need to see the projections through a HUD not an HMD.
Target tracked, gunner may keep camera locked if necessary. Allows simultaneous multiple target monitoring and position correlation.
Engage
Hard targets necessitate lase, infantry ones are typically just terrible. Reliance on a decent UAV Operator for a reliable lase. SDB onboard targeting is iffy at best on the server because ARMA 3 and really good reasons. Pain in the arse follow up capability as major time lag is necessarily incurred when next pass needs to be initiated which requires good spacing and high energy. Paradoxically, if one wants to maintain high energy for AA avoidance this reduces the window of opportunity in terms of completing yet another (partial) kill chain. Difficult to assess prudence of danger close occurrences.
Multi - mode tracking missiles, either SACLOS or thermal imaging. Kill chain completed within helicopter without external interference or assistance. Incredible effectiveness with follow up engagements as time lag is present only due to limitations of gunner awareness and speed of weapon cycling and follow up firing. Infantry eradication easy owing to a stationary position and cannon. Easy to assess prudence of danger close occurrences.
So, rotary CAS completes kill chains faster, independently, and the division of labor means OODA loop chains are finished with higher speed, even if one acts under the assumption of an (impossibly) perfectly coordinated UAV Operator and CAS pilot. Avoidance of AA with helicopters is not a complex matter, it's simply a few klicks of standoff. Of course this comparison acts under the assumption of no enemy CAS jets as a fair test. Exclusive rotary CAS without the removal of enemy jets is a lousy prospect for obvious reasons.
Rotary CAS is a good idea, it's far more engaging, less boring, and one can have tea while waiting without having to touch the actual stick.
