Sikorsky EH-60A Quick Fix II helicopter - development history, photos, technical data

Sikorsky EH-60A Quick Fix II
1981

The Army also acquired examples of two electronic warfare (EW) Blackhawk variants, designated EH-60A and EH-60B. Development of the former began in October 1980 when Sikorsky was awarded an Army contract to modify one UH-60A (probably 79-23301) for evaluation under the Quick Fix II EW programme. The modifications included preparation of the airframe for later installation of the AN/ALQ-151 multi-role tactical EW system, the addition of four dipole antennae mounted in pairs on either side of the tailboom, and the installation of a deployable whip antenna beneath the aft section of the main cabin. The EH-60A was also equipped with the AN/ALQ-144 infrared countermeasures set and flare/chaff dispensers in addition to the standard AN/APR-39(V)1 radar warning receiver. The YEH-60A EW Blackhawk flew for the first time in September 1981, and in October 1984 the Tracor Aerospace Group won an Army contract for the conversion of forty UH-60A to EH-60A standard. Flight testing of a planned 132 production -A model EW Blackhawks began in April 1986, though budget restraints ultimately led the Army to acquire only 66 production machines. The last of these was delivered in September 1989, and soon afterwards the type's designation was changed from EH-60A to EH-60C.

While the EH-60C is intended to locate, classify and disrupt enemy signals traffic, the EH-60B was developed specifically to carry the Stand-Off Target Acquisition System (SOTAS) radar. The EH-60B was characterized by the long box-shaped SOTAS scanner mounted below the main cabin, and was equipped with backward-retracting main landing gear legs to allow the SOTAS antenna to rotate a full 360 degrees in flight. The sole EH-60B prototype made its maiden flight in February 1981, but the SOTAS development programme was cancelled the following September and the aircraft was subsequently converted to EH-60A/C standard.

I started the year with a bad credit score, lingering debts and derogatory record which affected my ability to finance a new home, including a new car. I tried a few credit restoration firms but all were abortive until I saw a post about HACK VANISH CREDIT SPECIALIST. I reached out to them and surprisingly they helped cleaned-up my derogatory and raised my FICO score to 782 across all three bureaus, within a short period of time I got qualified for a new home, and also purchased my dream car. Anyone with related issues can reach out to them for assistance via [Hackvanish @ Gmail. Com] or Phone: (2 0 9 ) 3 3 0 - 3 0 4 7.

Oh yeah? If you picked up your blackhawks from Ramstein I probably saw you. We took them off of a c-5, got the rotor blades unfolded and got them test flown.

I flew the EH-60A out of Fulda West Germany along the E.W. German Border. in the late '80s. We had 3. They came to us right off the assembly line. Great birds.
Ezzy Black, e-mail, 24.02.2022 reply
At no point was the EH-60A designated the EH-60C, only the EH-60A. At least until the late 1990s it even shared a -10 with the UH-60A.

The EH-60C designation seems to have been reserved for a command and control aircraft, but never actually used by the Army.

Oh wow. I was an intel operator on EH-60s for nine years. And, well, I actually crashed in 571.

This was in 1995 and 571 was delivered the the CEWI plt of the 3rd ID at Hunter Army Airfield GA as a supplemental aircraft. Basically this happened during the draw-down of the 90's when many units were being deactivated. The EH-60s from those units were allocated to units remaining in service. I don't know what unit it was originally assigned to.

An incorrect push-pull tube was installed on the hydraulic deck resulting in the cyclic control locking up at a 100' hover. The resulting crash snapped off the right main landing gear and did some rather hefty damage to the belly as well as all 4 main rotor blades.

I never knew the status of it after it was hauled away. We assumed it would be repaired at a depot somewhere, but an entirely different helicopter was given to us shortly after.

I cannot give you any more history on it, the birds we flew in Desert Shield /Storm were our original aircraft, 24659, 572 and 574.

Great write ups on the EH60. I was very fortunate to be assigned Project Manager for the support role of this program back in 1997 after the closure of VHFS. When the aircraft was rejected from the Prophet Program it was sad day for me as a manager. I was tasked by DA to work with AVSCOM to strip all the fielded EH60's of their mission equipment and turn all the aircraft over to Ft. Rucker to become aircraft trainers, with exception of the one sent to NASA. These aircraft had the lowest air frame time in the Army inventory. I was honored to have flown on and supported this program and appreciated all the aircrews I meet. I also worked as the support manager with development of the AQF program and could not believe it would be scrapped.

I flew the EH-60A with the TN ARNG. Started Flying EW Aircraft w /the TNARNG in EH-1 HacJam System & the upgrade to the EH-60A airframe, & the QF system was necessary to make RW /EW Aircraft practical as the EH-1 airframe could not really support any real missions. While the the upgrade to the EH-60L airframe w /extended range, or in the EW series of aircraft extended "On-Station" time. In the end, however, I believe that the mission requirements, and added versitity, would have been better served if the Army had more forsight it would have gone with a CH-47C airframe, as with the additional space & electrical capacity to accommodate additional operator stations, & would still be more versitile (& more functional within the CH-47D airframe although the EH-60L does address the endurance questions that were present in the EH-60A, which should have been equipped with the drop tanks. With experience in both Aviation, & Military Intelligence, I have to say that perhaps initially there was some hesitation within the Intelligence Com$unity to bring on a RW-based platform, especially one based upon a widely distributed RW airframe, that would end up with the "collection asset" being operated at the "Tactical Commander's level. Their hesitancy was eventually justified when some field commanders unable to resist converting at least one of these air conditioned airframes into VIP use, not understanding that there was a specific reason why the EH-60's were deployed in a four (4) airframe unit. Add to those issues were the constraints that perhaps only became obvious after the airframes were fielded, that being the lack of the specialized experience and training that limited its efficacy when mission planning was done by an S-3 /G-3 shop under the direction of a non-Military Intelligce Branch officer, & flown by aviators who also lacked Intelligence Community experience. The "turf-battles" & lack of the institutional support at the deployment level demonstrated that assests such as these should be assigned to Military Intelligence Units and co-located with the RC-12 FW aircraft, & flow by aviators who had operational experience in flying collection assets.

As an operator and platoon sergeant with EH-60s for nine years I feel you missed the whole point of the aircraft. Making it larger and placing it in a CH-47 with additional operators etc removes the capability from the maneuver division which it was designed for. Indeed, during those 9 years I needed to only look across the tarmac at Hunter Army Airfield to see the fleet of RC-12 Guardrail aircraft the performed the mission you envision rather admirably (and still do).

To put it in perspective During Desert Storm the only SIGINT and EW capability available to the 24th Infantry Division was it's 3 EH-60s. No ground assets could hope to keep pace with the battle and indeed, they arrived two days after the war was over. One EH-60 of the three was literally in the air for the entire 100 hours.

No aircraft in the entire division came even close to the hours flown by EH-60s during the entirety of Desert Shield /Storm.

Mission duration was never an issue as FARPs were always available. While it did cause short breaks for hot-gas we simply went right back on station. Missions went for as long as we were allowed to fly in a day, 8 hours.

An EH-60 was a team. Those crazy intel guys in the back know what to do with them. It was generally understood that the pilots flew where we told them to, until they told us no. That is if there was some reason the aircraft could not be operated safely or within it's flight parameters the pilots had veto power. It was understood that the pilots had a fairly limited amount of training in what we were trying to accomplish.

As a new 2LT right out of flight school, I fielded the Quickfix Platoon for the 4th ID at Ft. Carson in the early 90s. We were the first Blackhawks in the division. Back then 4th ID was near the bottom of DoDs list and was near the bottom of the list to receive new equipment. There were Guard and Reserve units with higher priority than us. It was cool to be the first Blackhawks in the division, but the lack of maintenance support and infrastructure made it challenging. As mentioned above, my platoon was rarelytasked to perform the true Quickfix mission because of a lack of understanding by the Military Intelligence unit, my Aviation Regiment and even myself and fellow aviators. Most frequently we were a flying "re-trans" station to improve radio communications between aviation units performing other missions.

The Quickfix course at Ft. Huachuca taught us about the airframe, mission equipment and mission planning. We left knowing how to perform the mission but with little understanding of why to perform the mission. Add to that the limitations of the EH-60A in many ways made the aircraft impractical for the mission. That said, the members of my platoon did have a higher level of knowledge about employing the EH-60s because of our training and it was our job to try to educate those that would task us with our missions. Generally speaking O-5s and O-6s don't want to listen to brand new LTs.
And honestly, a young aviator like myself didn't want to be "boring holes in the sky".

This has a familiar ring to it. In 1967-68 I was at Da Nang supporting the RU-8D aircraft supporting 3rd Marine Division with Airborne Direction Finding. I think the design theory was, if there is room for it will fit. We flew four hour missions with a fifteen minute fuel reserve. Phantoms had wait for us to take off, and then another few minutes for us to clear the airspace so that they didn't run over us. They probably used more fuel waiting for us than we burned in four hours. If I remember correctly a Beechcraft rep refused to fly in our of out planes because he claimed that it was too heavy to fly. Bit we flew four mission every morning and four more every afternoon.
We were successful enough that the Navy awarded us a Meritorious Unit Citation for our support of 3rd Marine. The plane could not get much over 10,000 feet or fly faster than 126 Knots if memory serves me correctly. The RU-21 arrived a year late as I was leaving country.
They were interesting times!

We got around this by the simple expedient of requiring the EH-60 platoon leader to attend all MI BN staff meetings. He was always there reminding them that we worked for THEM and not the AVN BDE.

Did you have to have your aircraft modified for a re-trans capability? That seems odd to me unless the cockpit UHF radios always had the capability and I didn't know about it. Still, we would have never flown a mission for the aviation brigade. That just seems like a foreign concept.

I was one of those crazy Intel guys in the back. Our rotor jocks knew the Intel mission sufficiently to utilize flight ops to ensure EW collection. As crew, missions were 12 hours, jockeys could OP for 8 hours daylight, 4 hours night ops. Crews could go 12 hours with pilot swaps. Mandatory service time.

QuickFix defenses were awesome and the pilots we worked with at 107th MI /7th ID (LIGHT) prior to, during, and after Desert Shield / Storm had great confidence in the airframe.

Hey Mike. I think the tail number of the bird you crewed was 87-24668. The tail number you listed might have been our VIP bird. The other two EH birds were 86-23573 and 87-24669. I am currently working with 87-24657 here at Moffett Field. It has been repurposed as strictly a research bird here at NASA.
