RAH-66 Comanche missing avionics

The RAH-66 Comanche on the dev server is currently missing access to various avionics equipment such as an RWR, IR/RF jammers, and chaff dispensers.

The report will probably be shot down as Jane’s is not considered a reliable source.

It might be worth consulting the following documents as they may have other data :

Appendix E; PDF page #76

Aircraft Survivability Equipment (some optional):
Low Observable Materials
AN/APR-39 A(V)1 Radar Warning Receiver

Appears that the RAH-66 should have a wide FoV HMD


other interesting excerpts include;

The COMANCHE exploits stealth technology and design in its airframe to reduce its signature on the battlefield. Constructed of low observables, the RAH-66 scout configuration has a radar signature 663 times less than that of the AH-64A and several hundred times smaller than the OH-58D KIOWA WARRIOR. Its thermal signature is less than half of that of the APACHE and on par with the KIOWA WARRIOR." This signature is so low that a STINGER missile cannot lock onto it.

Its visual signature approximates that of the AH-1 COBRA, and its acoustic signature is about that of an OH-58D.87 These characteristics will greatly reduce the threat’s ability to detect the RAH-66.

The COMANCHE employs a suite of target acquisition sensors much like that of the
AH-64D
, however, its FLIR sensor is vastly improved. The COMANCHE employs a
second-generation FLIR system that provides up to 53% greater detection range, 93%
greater classification range, and 107% greater identification range than the AH-64D’s
system.

Working on the report now; Is live.

Nice, in those documents was there anything about IR jammers for the Comanche or did it just give that RWR?

Yes, ALQ-144(V)3. Same excerpt.

It should be slightly more effective than the -144 on the AH-1F, due to using advanced waveforms

Awesome, just managed myself to find it in that document, seems like it should have some more bits aswell including chaff dispensers

Are you planning to make some more reports on those by any chance? If not I’ll have a stab at them when I can.

Do what you can.

It (the M-130) should also be able to carry Flares (?M206?) as well, but it’s doctrinal due to the presence of the IR jammer that they wouldn’t be needed.

Probably it won’t lead to anything, but I’ll leave it here.

Now for the RWR systems…

Comanche’s Suite of Integrated Radio Frequency Countermeasures (SIRFC) comes from ITT Avionics in Clifton, N.J. The SIRFC (ALQ-211[V]3) is a stand-alone radar-warning receiver designed to provide radar warning, situational awareness, and electronic countermeasures to help the Comanche detect, evade, and defeat modern and emerging air defense threats.

The Comanche program had a long development period, so the subsystems also had changes accordingly (e.g., the addition of the Longbow radar).

AFAIK The AN/APR39(v)1 was the initial specification, and it seems that the seemingly more advanced ALQ-211(v)3 was planned later. Sadly, however, the ALQ-211(v)3 was developed for the Comanche, so it disappeared along with the Comanche when it was canceled. So what the specifications of this were can only be guessed at through other versions.

Going back to 1993, we were visited by a representative from OSD who ran all the government R&D facilities. With him were all the directors of the labs. Their task was to coordinate their activities to support the technology needs of the program. We used optimistic weight assumptions based on their projections. As Army funding was reduced, the lab support disappeared, along with our optimistic weight projections. As for growing Army requirements, there were a total of 85+ user operational requirements document (ORD) changes from 1991 to 2001. These included:

Radar warning receiver (RWR) • Radar frequency interferometer (RFI) • Armor • High frequency (HF) radio • Radar cross section (RCS) combat kits • Link 16 • SATCOM • SADA • Fifth-percentile female • Integrated mission support system (IMSS) • Air bags • Image-intensified charge-coupled device TV camera (I2 on nose) • Internal weapons bay fuel tanks • Two-axis seats for the fifth-percentile female • Chemical detectors • Two-station external fuel and armament management system (EFAMS) • Increased gun rounds • Growth T800 engines

Is this the HSTV-L of the sky? Practically being a completely different vehicle in-game than real life, the only thing being the same is the visual model…

any reports on the missing air to air loadouts?
