    Recently, I obtained some fascinating photographs of car-rier operations of a quartet of rather anonymous ChanceVought F7U-3 Cutlass ghters. Whilst trying to nd outwhat was going on i n the photographs, I was able to piecetogether the story of Project Cutlass, which is describedin the article below:

    The early 1950s were an era of rapid improvements and de-velopments in worldwide aircraft design; it was the time that jetghters became a viable alternative to piston-engined ghters,at the same time these ghters were routinely challenging thesound barrier. In operational service, the career of these earlyghters was often short, with successors looming around thecorner before a type had been fully introduced in service. Forthe US Navy, it was an era of ghters like the F9F Panther and

    Cougar, F2H Banshee, F3H Demon, F4D Skyray, FJ Fury andthe F7U Cutlass. Some challenged the boundaries of what wastechnically possible, while others played it safe, to an extent.

    Some types were more successful than others, and one thatcertainly was not, was the Vought F7U Cutlass.

    For its time, the Cutlass was a highly advanced ghter design;it was the rst tail-less ghter to enter full-scale production, itwas the Navys rst swept-wing ghter, it was the rst one witha steerable nose wheel and, most importantly, it was the rst

    jet ghter in the USA to be designed with afterburning engines(the experimental F6U Pirate had been modied to become therst aircraft to use afterburners). Unfortunately, it were thesevery engines, as well as a problematic hydraulic system andnose landing gear, that would play a large part in the aircrafts

    How the Chance Vought F7U-3 entered serv ice

    F7U-3 129662 starts to accelerate down the new C-11 steam catapult of the USS Hancock. As can be seen here, the Project Cut-lass F7U-3s carried very plain markings, with just the NAVY on the tail and code 1 on the nose. All photographs in this article weretaken during June and July 1954. They have languished in the archives of the Vought Retirees Club for years, where Mark Nankivilrescued them and shared them with us.

    The quartet of F7U-3s which prompted this article, tied down on the USS Hancock while in port. From left to right: 129662/1,129657/4, 129637/2 and 129678/3. In this photograph, the aircraft carry the under-fuselage rocket pod, which they do not in mostof the other photographs in this article.

    demise. If it had been powered by a good engine, the storymight have been different. To be fair, the aircrafts ying charac-teristics were excellent in general; it was able to outmaneuvermost of the other ghters of the era and every pilot loved yingthe aircraft. Development of the Cutlass started in 1948 and therst F7U-1, 122472, made its rst ight on 28 September 1948.

    After a few years of troublesome test ights with the NATC, car-rier qualications were conducted on board the USS Midway inJuly 1951, which revealed even more shortcomings in the basicdesign of the aircraft, one of these being insufcient forwardview over the nose due to the types extreme angle-of-attackapproach stance. The ndings rendered the F7U-1 unsuitablefor squadron service. In the meantime, work had started on theimproved F7U-2 and the even more radically altered F7U-3; it

    was the latter that was eventually taken into production. TheF7U-1s did not have the structural airframe integrity to sustaincarrier operations, but the F7U-3 airframe had been built like atank. The initial sixteen machines still had the Allison J35 en-gine of the F7U-1 installed, but later machines all had the morepowerful Westinghouse J46 engine.

    Carrier qualications with the F7U-3 were conducted on boardthe USS Midway and USS Coral Sea in late 1952. With all theproblems experienced during testing with the F7U-1 and -3,

    putting the Cutlass in operational service asked for some cau-tion and while the initial development problems were wrinkledout at the NATC, a different approach was chosen to start oper-ational testing of the Cutlass. Usually, the operational test units

    like VX-3 and VX-4 would do most of thework, but this time, although both VX-3 andVX-4 did operate the F7U, Project Cutlasswas initiated by HQ ComAirPac as a unitcharged with gaining operational familiari-zation, maintenance knowledge and logis-tics data prior to the Cutlasss assignment tothe rst operational eet squadron. In short,they had to write the book on how to oper-ate the Cutlass in eet squadrons. The planwas that the unit was to form the nucleus

    of the rst operational Cutlass squadron,which turned out to be VF-124.

    At 11:16 on 2 February 1954, six minuteslate, 128477, the rst F7U-3 for ProjectCutlass, arrived at NAS Miramar from theChance Vought factory in Dallas. The ar-rival was viewed by a large crowd of linecrews all eager to get their rst look of oneof the fabled new Cutlasses. It was own inby LCDR R. G. Puckett; he was greeted byCapt D. L. Mills, Miramars commanding of-cer, and LCdr J. S. Brown, the Project Cut-lass C/O. On the way to Miramar, Pucketthad caused quite a stir at El Paso Municipal

    Airport (TX); he practically single-handedlydisrupted airport operations during the tran-sient stop; his Cutlass attracted tht muchattention from airport personnel that all oth-er activities ground to a halt! The ProjectCutlass F7U-3s were ofcially assignedto FASRON-12, a support unit at Miramarwhich was responsible for maintainingthe aircraft. FASRON-12 supplied specialproject personnel, along with hangar space.They also took care of the administrative

    Three of the Project Cutlass F7U-3s in ight over California, photographed from a TV-2 as related in the text. The formation is ledby 129637/2, trailed by 129657/4 and 129678/3.

    be seen, the Cutlass nosewheel strut hadbeen lengthened to gigantic proportions toimprove the airow over the aircrafts wings,but this size was a contributing factor in themany nose gear failures experienced by theCutlass.

    and operational control of Project Cutlass. As more F7U-3s were delivered to the unitand more experience was gained, the paceof operations increased and by July 1954,the unit had reached its full complement oftwelve Cutlasses.

    The units ofcers and enlisted men weremostly hand-picked as being the best intheir eld. For instance, the squadronsmaintenance ofcer, Lt Robert D. Belt, had

    been the maintenance ofcer for the Blue Angels before being reassigned to ProjectCutlass. One of the units pilots was LtWalter Wally Schirra, who was the unitsweapons expert and would later becomean astronaut, being involved in the Mer-cury, Gemini and Apollo space programs;he was eventually launched into spacethree times. He thought the aircraft was alearning experience for both the Navy andChance Vought; it taught them delta wingaerodynamics and how to operate an air-craft with an afterburner. Two other pilotswere Don Shelton, operations ofcer, andFloyd Nugent, both graduates of the Test Pi-

    lot School at NAS Patuxent River; all of theProjects initial cadre of pilots had receivedacademic and ying training on the Cutlassat the Chance Vought plant in Dallas. Therst group of pilots completed the course inDecember 1953. Stories and photographsof the Cutlass had been around for a fewyears, and initially, each of the Projectspilots was very eager to y this futuristic

    jet ghter. The units ground crews learnedthe tricks of the trade in a mobile trainingunit, detached to Miramar from NATTCMemphis. This course lasted two weeks.This training unit included complete work-able models of the hydraulic, electrical and

    mechanical systems of the F7U-3, as wellas several other important components.For the pilots, there was a working cock-pit model, complete with lighting, wherethey were able to get acquainted with theswitches and dials.

    The unit quickly started ying like an op-erational squadron, this was known as theying wing phase of the ghters develop-ment process. Initially this was limited tooperations ashore. Their aim was to look

    The Project Cutlass pilots carried out FCLP at OLF Crows Landing, which was anauxiliary aireld located about 50 miles east of NAS Moffett Field, it was used as arelief landing ground for Moffett Field.

Note the extreme nose-high position of theCutlass while on the gropund.

    Below are the service histories of the four F7U-3s identied on the photographs. Please note that Project Cutlass is not mentionedin these histories (apart from the codes carried by the aircraft); for al l purposes the aircraft were ofcially assigned to FASRON-12,a support and maintenance unit based at NAS Miramar.

    129637 Accepted 30apr54 and assigned to FASRON-12 on 06may54. Coded 2 while ying with Project Cutlass. Transferredto VF-124 on 13oct54, but returned to FASRON-12 24jun55. On 13oct55 the aircraft was transferred to NAS NorthIsland (most likely to the NARF there) and went back to Vought at NAS Dallas on 30mar56. Between 23oct56 and19dec56 it spent time at NAS Corpus Christi (purpose unknown), went back to North Island on the latter date and wasofcially scrapped (or reduced to spares, as the US Navy calls it) on 30jul58.

    129657 Accepted on 11jun54 and assigned to FASRON-12 on 03sep54. Coded 4 while ying with Project Cutlass. Trans-ferred to VF-124 on 13oct54 and returned to FASRON-12 on 08jul55. Reassigned to VF-151 on 02nov55. Went toVought at NAS Dallas on 25apr56 and to NAS North Island (most likely the NARF there) on 21sep56. It was thenreassigned to VA-126 on 30oct56. Placed in storage at NAF Litcheld Park on 09apr57 and nally SOC on 22jul58.

    129662 Accepted on 11jun54 and assigned to FASRON-12 on 04sep54. Coded 1 while ying with Project Cutlass. Trans-ferred to VF-124 on 13oct54 but returned to FASRON-12 on 08jul55. Went back to Vought at NAS Dallas on 20oct55and moved to NAS North Island on 30mar56, where it was WFU and ofcially reduced to spares (i.e. scrapped) on

    23jan57.129678 Accepted on 31aug54 and assigned to FASRON-12 on 10oct54, Coded 3 while ying with Project Cutlass. It was

    transferred to VF-124 on 13oct54. Went back to Vought at NAS Dallas on 07nov55 and moved back to NAS NorthIsland on 24apr56. It was transferred to VA-126 on 24may56, but was placed in storage at NAF Litcheld Park on09apr57 and was nally SOC on 22jul58.

    four-engined airliner into the air which in this case must havebeen a DC-6 or Constellation. On 15 February 1954, Hancockhad been recommissioned after receiving the latest carriermodications, including the new catapult. In 1954, the carrieralso performed the rst at-sea Sparrow I missile rings and sup-ported the new Regulus missile test program. On some days,the pace of operations was frantic, with aircraft being launched,y a circuit or two, trap, before being launched yetagain. Actually, so many launches were made,that dropping the catapult bridle into the seaduring every launch was deemed to be too ex-pensive. Bungee cords attached the bridles tothe nose gear and for a time, the aircraft did notretract the undercarriage following launch, justew a circuit and trapped on board the carrieragain, all of this with the bridle still in place.One quick change was made to the carrier: ablast deector was designed and installed todeect the jet blast away from the carriersdeck, which was still made of wooden plankingin those days. The aircrafts afterburner amehad a tendency to scorch these, necessitatingregular replacement of the planks. The deec-tor, made of a metal mesh, was a device whichrose vertically from the deck. Floyd Nugent,ying an F7U-3 not in the photographs in thisarticle, experienced an interesting emergencyduring one of these tests: upon take off, thenose wheel simply dropped into the sea! Hecircled around in the vicinity of the Hancock,while he and the crews on the carrier deliber-ated what to do next. It was decided that hehad to eject. At that moment, he was overyingCoronado, and was headed for the ocean. Heejected over NAS North Island, but after land-ing safely he discovered to his horror that dueto the ejection and the absence of the weightof the seat and pilot, the centre of gravity hadshifted and the aircraft was now ying a perfectcircular course over the NAS! It was consid-ered to shoot it down, but the dangers of theaircraft crashing into houses was too great andafter about 30 minutes fuel ran out and the air-craft made a perfect unmanned landing in thesea just offshore! If it had not been for the saltwater corrosion, it could have been repaired toy another day.

    Despite the apparent success and the favora-ble ying characteristics, the Project Cutlasspilots decided that the aircraft was too compli-cated to y for inexperienced pilots and it wasrecommended that it was not to be used foreet service. Wally Schirra was not too fond ofthe Cutlass and he described it as an accidentwaiting to happen. Apart from the engine andlanding gear problems, another serious vicewas the post-stall gyration. If the aircraft wasstalled with the slats out, there was no prob-lem. But if it stalled with the slats in, the planewent into wild and random motion and the onlyway out was to eject! However, all these rec-ommendations against eet use were put asideand the aircraft was accepted for eet use any-way, with disastrous results.

    When Project Cutlass wound down at the endof 1954, six aircraft were transferred to the ini-tial Cutlass training unit, VC-3 at NAS MoffettField (CA). Among a few other types, VC-3 wasstill ying F4U-5N Corsairs in 1954! The unit be-

    came involved in prop-to-jet transition trainingas the Cougar College of Supersonic Knowl-edge, ying the Fury, Cougar and Demon, andnow the Cutlass as well. First F7U class start-ed in November 1954. The Projects other sixF7U-3s went to VF-124, including the Projects

    former C/O, LCDR J S Bud Brown. These aircraft formed thenucleus of the Navys rst operational Cutlass squadron, whichwas to make the rst operational Cutlass cruise on board Han-cock in August 1955. With the transfer of the aircraft, ProjectCutlass was discontinued, the task of bringing the F7U-3 up tooperational speed completed.

    Over the next few years, the F7U-3 was successfully intro-

    duced into operational service, butsubstantial difculties were encoun-tered. One of the greatest problemsthat remained during the operationalservice life was the aircrafts longnose gear. Although it had beenstrengthened, the aircraft had a ten-dency to trap on board a carrier noserst and the whiplash effect causedregular nose gear collapses. Duringthe 1954-1955 VF-81 Med cruise onthe USS Ticonderoga, a nose gearcollapse, and the squadrons inabil-ity to properly repair this, caused theunit to be stationed ashore at PortLyautey during the rest of the cruise.VA-66 (USS Ticonderoga, 1956) andVA-83 (USS Intrepid, 1956) also suf-fered the same problems during theircruise. The nal Cutlass cruise wasmade by VA-116 on board the USSHancock. When they returned homein September 1957, the unit startedconverting to FJ-4B Furies. Thiswas the end of the line for the F7UCutlass, also known as the EnsignEliminator or Gutless Cutlass; it hadbeen in operational service for justthree years and bluntly said: it hadbeen a disaster.
