HobbyBoss A-4F Sky Hawk

Post by Kevthemodeller »

My next build an A4-F Sky Hawk 'Bobbie' NF400 VA-94 ‘Mighty Shrikes’ Attack USS Bon Homme Richard Gulf of Tonkin in circa 1968 - 69.

From Wikipedia: A good read if you're minded :th:

The Douglas A-4 Skyhawk is a single-seat subsonic carrier-capable attack aircraft developed for the United States Navy and United States Marine Corps in the early 1950s. The delta-winged, single turbojet engined Skyhawk was designed and produced by Douglas Aircraft Company, and later by McDonnell Douglas. It was originally designated A4D under the U.S. Navy's pre-1962 designation system.

The Skyhawk is a relatively lightweight aircraft with a maximum takeoff weight of 24,500 pounds (11,100 kg) and has a top speed of more than 670 miles per hour (1,080 km/h). The aircraft's five hardpoints support a variety of missiles, bombs and other munitions. It is capable of carrying a bomb load equivalent to that of a World War II–era Boeing B-17 bomber, and can deliver nuclear weapons using a low-altitude bombing system and a "loft" delivery technique. The A-4 was originally powered by the Wright J65 turbojet engine; from the A-4E onwards, the Pratt & Whitney J52 engine was used.

Skyhawks played key roles in the Vietnam War, the Yom Kippur War, and the Falklands War. Sixty years after the aircraft's first flight in 1954, some of the 2,960 produced (through February 1979)remain in service with the Argentine Air Force and the Brazilian Naval Aviation.

Design and development

The XA4D-1 prototype in 1954
The second production A4D-1

The Skyhawk was designed by Douglas Aircraft's Ed Heinemann in response to a U.S. Navy call for a jet-powered attack aircraft to replace the older Douglas AD Skyraider (later redesignated A-1 Skyraider). Heinemann opted for a design that would minimize its size, weight, and complexity. The result was an aircraft that weighed only half of the Navy's weight specification.[3] It had a wing so compact that it did not need to be folded for carrier stowage. The first 500 production examples cost an average of $860,000 each, less than the Navy's one million dollar maximum. The diminutive Skyhawk soon received the nicknames "Scooter", "Kiddiecar", "Bantam Bomber", "Tinker Toy Bomber", and, on account of its speed and nimble performance, "Heinemann's Hot-Rod". The XA4D-1 prototype set a world speed record of 695.163 mph on 15 October 1955.

The aircraft is of conventional post-World War II design, with a low-mounted delta wing, tricycle undercarriage, and a single turbojet engine in the rear fuselage, with two air intakes on the fuselage sides. The tail is of cruciform design, with the horizontal stabilizer mounted above the fuselage. Armament consisted of two 20 mm (.79 in caliber) Colt Mk 12 cannons, one in each wing root, with 100 rounds per gun (the A-4M Skyhawk II and types based on the A-4M have 200 rounds per gun), plus a large variety of bombs, rockets, and missiles carried on a hardpoint under the fuselage centerline and hardpoints under each wing (originally one per wing, later two).

The short-span delta wing did not require the complexity of wingtip folding, saving an estimated 200 pounds (91 kg). Its spars were machined from a single forging that spanned across both wingtips. The leading edge slats were designed to drop automatically at the appropriate speed by gravity and air pressure, saving weight and space by omitting actuation motors and switches. Similarly the main undercarriage did not penetrate the main wing spar, designed so that when retracted only the wheel itself was inside the wing and the undercarriage struts were housed in a fairing below the wing. Thus the wing structure was lighter with the same overall strength. The rudder was constructed of a single panel reinforced with external ribs.

The turbojet engine was accessed for service or replacement by removing the aft section of the fuselage and sliding out the engine. This obviated the need for access doors with their hinges and latches further reducing weight and complexity. This is the opposite of what can often happen in aircraft design where a small weight increase in one area leads to a compounding increase in weight in other areas to compensate, creating a demand for more powerful, heavier engines, larger wing and empennage area, and so on in a vicious circle.

The A-4 pioneered the concept of "buddy" air-to-air refueling. This allows the aircraft to supply others of the same type, reducing the need for dedicated tanker aircraft—a particular advantage for small air arms or when operating in remote locations. This allows for greatly improved operational flexibility and reassurance against the loss or malfunction of tanker aircraft, though this procedure reduces the effective combat force on board the carrier. A designated supply A-4 would mount a center-mounted "buddy store", a large external fuel tank with a hose reel in the aft section and an extensible drogue refueling bucket. This aircraft was fueled up without armament and launched first. Attack aircraft would be armed to the maximum and given as much fuel as was allowable by maximum takeoff weight limits, far less than a full tank. Once airborne, they would then proceed to top off their fuel tanks from the tanker using the A-4's fixed refueling probe on the starboard side of the aircraft nose. They could then sortie with both full armament and fuel loads. The A-4 was rarely used for refueling in U.S. service after the KA-3 Skywarrior tanker became available aboard the larger carriers. The versatility of the capability and the retirement of the Skywarrior meant that the Boeing F/A-18E/F Super Hornet now includes this capability.

Thermal cockpit shield for nuclear weapons delivery
The A-4 was also designed to be able to make an emergency landing, in the event of a hydraulic failure, on the two drop tanks nearly always carried by these aircraft. Such landings resulted in only minor damage to the nose of the aircraft which could be repaired in less than an hour.

The Navy issued a contract for the type on 12 June 1952, and the first prototype first flew from Edwards Air Force Base, California on 22 June 1954.[13] Deliveries to Navy and Marine Corps squadrons (to VA-72 and VMA-224 respectively) commenced in late 1956.

The Skyhawk remained in production until 1979, with 2,960 aircraft built, including 555 two-seat trainers. The last production A-4, an A-4M of Marine squadron VMA-331 had the flags of all nations that operated the A-4 painted on its fuselage sides.

Operational history
United States
The Skyhawk proved to be a relatively common United States Navy aircraft export of the postwar era. Due to its small size, it could be operated from the older, smaller World War II-era aircraft carriers still used by many smaller navies during the 1960s. These older ships were often unable to accommodate newer Navy fighters such as the F-4 Phantom II and F-8 Crusader, which were faster and more capable than the A-4, but significantly larger and heavier than older naval fighters.

The Navy operated the A-4 in both Regular Navy and Naval Reserve light attack squadrons (VA). Although the A-4's use as a training and adversary aircraft would continue well into the 1990s, the Navy began removing the aircraft from its frontline attack squadrons in 1967, with the last ones (Super Foxes of VA-55/212/164) being retired in 1976.

The Marine Corps would not take the U.S. Navy's replacement warplane, the LTV A-7 Corsair II, instead keeping Skyhawks in service with both Regular Marine Corps and Marine Corps Reserve attack squadrons (VMA), and ordering the new A-4M model. The last USMC Skyhawk was delivered in 1979, and they were used until the mid-1980s before they were replaced by the equally small, but more versatile STOVL AV-8 Harrier II.

VMA-131, Marine Aircraft Group 49 (the Diamondbacks) retired its last four OA-4Ms on 22 June 1994. Trainer versions of the Skyhawk remained in Navy service, however, finding a new lease on life with the advent of "adversary training", where the nimble A-4 was used as a stand-in for the Mikoyan-Gurevich MiG-17 in dissimilar air combat training (DACT). It served in that role at TOPGUN until 1999.

The A-4's nimble performance also made it suitable to replace the McDonnell Douglas F-4 Phantom II when the Navy downsized its aircraft for the Blue Angels demonstration team, until McDonnell Douglas F/A-18 Hornets were available in the 1980s. The last U.S. Navy Skyhawks, TA-4J models belonging to the composite squadron VC-8, remained in military use for target towing, and as adversary aircraft, for combat training at Naval Station Roosevelt Roads. These aircraft were officially retired on 3 May 2003.

Skyhawks were well loved by their crews for being tough and agile. These attributes, along with their low purchase and operating cost as well as easy maintenance, have contributed to the popularity of the A-4 with American and international armed forces. Besides the U.S., at least three other nations have used A-4 Skyhawks in combat (Argentina, Israel, and Kuwait).

Vietnam War era

VA-146 A-4Cs over the Gulf of Tonkin in August 1964; USS Kearsarge steams below.
Skyhawks were the U.S. Navy's primary light attack aircraft used over North Vietnam during the early years of the Vietnam War; they were later supplanted by the A-7 Corsair II in the U.S. Navy light attack role. Skyhawks carried out some of the first air strikes by the US during the conflict, and a Marine Skyhawk is believed to have dropped the last American bombs on the country.[citation needed] Notable naval aviators who flew the Skyhawk included Lieutenant Commanders Everett Alvarez, Jr. and John McCain, and Commander James Stockdale. On 1 May 1967, an A-4C Skyhawk piloted by Lieutenant Commander Theodore R. Swartz of VA-76 aboard the carrier USS Bon Homme Richard, shot down a North Vietnamese Air Force MiG-17 with an unguided Zuni rocket as the Skyhawk's only air-to-air victory of the Vietnam War.

From 1956 on, Navy Skyhawks were the first aircraft to be deployed outside of the U.S. armed with the AIM-9 Sidewinder. On strike missions, which was the Skyhawk's normal role, the air-to-air armament was for self-defence purposes.

In the early to mid-1960s, standard U.S. Navy A-4B Skyhawk squadrons were assigned to provide fighter protection for anti-submarine warfare aircraft operating from some Essex-class U.S. anti-submarine warfare carriers, these aircraft retained their ground- and sea-attack capabilities. The A-4B model did not have an air-to-air radar, and it required visual identification of targets and guidance from either ships in the fleet or an airborne Grumman E-1 Tracer AEW aircraft.

Lightweight and safer to land on smaller decks, Skyhawks would later also play a similar role flying from Australian, Argentinean, and Brazilian upgraded World War II surplus light ASW carriers, which were unable to operate most large modern fighters. Primary air-to-air armament consisted of the internal 20 mm (.79 in) Colt cannons and ability to carry an AIM-9 Sidewinder missile on both underwing hardpoints, later additions of two more underwing hardpoints on some aircraft made for a total capacity of four AAMs.

The first combat loss of an A-4 occurred on 5 August 1964, when Lieutenant junior grade Everett Alvarez, of VA-144 aboard USS Constellation, was shot down while attacking enemy torpedo boats in North Vietnam. Alvarez safely ejected after being hit by anti-aircraft artillery (AAA) fire, and became the first US Naval POW of the war; he was released as a POW on 12 February 1973. The last A-4 loss in the Vietnam War occurred on 26 September 1972, when USMC pilot Captain James P. Walsh, USMC of VMA-211, flying close air support from Bien Hoa Air Base, South Vietnam, was hit by ground fire during the Battle of An Lộc. Captain Walsh ejected safely and was the last U.S. Marine to be taken prisoner during the war. He was released as a POW on 12 February 1973.

Although the first A-4Es were flown in Vietnam in early 1965, the A-4Cs continued to be used until late 1970. On 1 June 1965, the Chu Lai Short Airfield for Tactical Support (SATS) was officially opened with the arrival of eight A-4 Skyhawks from Cubi Point, Philippine Islands. The group landed with the aid of arresting cables, refueled and took off with the aid of JATO, with fuel and bombs to support Marine combat units. The Skyhawks were from Marine Attack Squadron VMA-225 and VMA-311.[24]

Armed A-4Fs on USS Hancock in 1972
On 29 July 1967, the aircraft carrier USS Forrestal was conducting combat operations in the Gulf of Tonkin during the Vietnam War. A Zuni rocket misfired, striking an external tank on an A-4. Fuel from the leaking tank caught fire, creating a massive conflagration that burned for hours, killing 134 sailors, and injuring 161.

During the war, 362 A-4/TA-4F Skyhawks were lost due to all causes. The U.S. Navy lost 271 A-4s, the U.S. Marine Corps lost 81 A-4s and 10 TA-4Fs. A total of 32 A-4s were lost to surface-to-air missiles (SAMs), and one A-4 was lost in aerial combat to a MiG-17 on 25 April 1967.

VA-94 From the internet: http://www.seaforces.org/

The Mighty Shrikes were redesignated as Light Attack Squadron 94 in 1958 and moved to NAS Lemoore, California in 1962. VA-94 aviators flew all models of the A-4 Skyhawk before transitioning to the A-7 Corsair II in February 1971.
The Mighty Shrikes completed seven consecutive combat deployments to Southeast Asia, commencing with a cruise aboard USS RANGER in 1964. In 1965, as part of Air Wing 9, the squadron was airlifted to Norfolk to join USS ENTERPRISE on her first combat cruise. The squadron was assigned to Air Wing 5 in 1966 and completed four combat deployments aboard USS HANCOCK and USS BON HOMME RICHARD. After transitioning to the A 7 Corsair II, the squadron was assigned to Air Wing 15 and completed its final Southeast Asia combat deployment aboard USS CORAL SEA. VA-94 aircraft led the first major Navy bombing strikes into North Vietnam after the 1968 bombing halt and participated in the mining of Haiphong harbor.

In 1973, the squadron deployed on its first peacetime cruise in a decade, again with Carrier Air Wing 15 aboard USS CORAL SEA. In 1975, the Mighty Shrikes participated in Operation FREQUENT WIND, the Saigon evacuation that terminated United States military involvement in Vietnam. Shortly thereafter, the squadron participated in the recovery of SS MAYAGUEZ after its seizure by Cambodia. From May 1979 to January 1980, the squadron deployed aboard USS KITTY HAWK to the Western Pacific and Indian Oceans, including 63 days of operations in the Arabian Sea during the Iran Hostage Crisis. The squadron's next deployment aboard USS KITTY HAWK was completed in 1981.
In January 1982, the Mighty Shrikes joined Carrier Air Wing 11 and deployed aboard USS ENTERPRISE. A Navy milestone was set in April 1983 when VA-94 became the first single engine tactical aircraft squadron to fly across the Pacific Ocean from the Philippines to the United States. In May 1984, the Mighty Shrikes deployed again aboard USS ENTERPRISE to the Western Pacific and Indian Oceans.

In 1986, aboard USS ENTERPRISE, VA-94 made history as part of the first nuclear aircraft carrier to transit the Suez Canal. The Shrikes cruised the Mediterranean for three months, supporting operations against Libya.

In 1988, during their 19th deployment, the Mighty Shrikes again made history by striking the naval forces of Iran as part of Operation PRAYING MANTIS, the first major U.S. naval battle since World War II. In October 1988, VA-94 received the coveted LTJG Bruce Carrier Award for excellence in Aviation Maintenance.

In the fall of 1989, the Mighty Shrikes deployed again aboard USS ENTERPRISE. After completing a world cruise, the Mighty Shrikes retired their trusty, battle proven A-7E Corsairs. This successful deployment was marked by winning the CNAP Battle "E."

In June 1990, the Mighty Shrikes received their first FA-18C, Lot XII Hornet and were redesignated Strike Fighter Squadron 94.

Not sure if I should be asking this here, but I was reading the history of this craft you posted. You said this craft is still in service in South America and it came to my mind that is a awful long time to be flying at over 1000km/hr for 40yrs in fact. Obviously a lot of time is on the ground, but what does that do to a air frame. Land based vehicles can look a bit shonky after that amount of time and don't have the same landing/takeoff stresses and combat maneuvers. Are there sheared rivets and wing spars that must be replaced.

I did think much the same mate. I did a bit of digging and apparently the aircraft was built so well, over engineered in fact. Tests prove (from Vietnam) even flying flat out at combat speeds and levels, the air frame can take something like 15k hrs, the original design spec was for 4k hrs. So it's life is almost indefinite This is a very interesting Doc about the A4 the section about serviceability is 34.42 on wards :th:

I never made one as a kid/teenager so this is my first, think it got overlooked by the more sexier aircraft at the time like the F14, 15 etc.

Last few days of bench time, lots of seem work, assembling the undercarriage and weapon pylons :th:

Wings on
Image
The frontal area where the wing meets the fuselage was a real challenged, I got so engrossed I for got to take pictures of the before fit :doh: Although the fit was good it wasn't great and lack constancy, especially the right angle section right at the front of each wing route. I had to remove material and replace it, I used extended sprure for the latter, lot of work but I'm happy with the results thus far. They will need further filling once primed but only so as to give the lines a more uniformed appearance :th:

Hi Matt sorry for the delay in replying been busy last few days. The kit is pretty good, the fit is mostly of a high standard, some areas are not and require some thought and work, these I've highlighted in my build log. It's not Tamiya latest offerings levels but it's cheaper. I've also got their F-14B which is better than this kit looking in the box and again somewhat cheaper than Tamiya, whether it's any better only time will tell. I would recommend the kit, providing you understand areas will need considerable work if like me your into trying to produce the very best you can. If you're just wanting to put it together, paint it, your are still going to get a nice model, just one that will bear detailed inspection. :th:

Superb work on the cockpit Kev and the rest of it's coming together really nicely too - looking forward to seeing it move along.

As you mentioned in the intro it's a really neat looking aircraft that often gets overlooked.

Last few days have been slow going building the Mk82 bombs and pylons, these are made up of 26 parts each side some are very fiddly :crazy: No the left is the parts on the right is one side assembled ready for painting.
Image
I think there's a mistake in the kit, these are with the bomb securing brackets :wtf: the ones down the sides are attached by there being a very small right angle step which corresponds to a step on the pylon.
Image
Image
Image
The lower or underneath bracket which will mount on to what is the top of the pylon in this picture, you will see the 2 mounting areas are flat. Yet the brackets have the right angle as per the side mountings, I had to cut this and make good the brackets so they would fit :wtf: :wall: Modified on the right.
Image
Fully assembled and inculding the A9's which were straightforward :th: This lot took 7 hrs of assembly and

Looking good. That's a serious weapons load for such a small aircraft. Just shows how much things changed 20 years after WWII. Single seat fighters carrying loads like a B17!
Its been tried and tested, it works! So don't blame the system if you're no good. :doh:

That's a lot of ordnance and some major fiddly bits by the looks of it too - nice going Kev!

Sure is now I'm trying to work out where it all goes, as the instructions aren't quite clear :crazy:

Looking forward to this one as it's on my 'just about to purchase' list. Incidentally there's three Skyhawks in daily use by the private firm Draken in Germany at the moment providing the same service as Cobbham Falcons do in the UK.

Been very busy finishing and painting the undercarriage, weapons load, boy there's a lot of it, the bombs needed quite a bit of work :crazy: Still got decals and final weathering to do.
Image

Finished off the fuselage/wings and primed them :th:
Image
Noticed the intakes to fuselage join needed some more work, so filled using stretched sprue :th:
Image
Rubbed down came up a treat, just a good few hours more work :crazy: :th:

Reprimed :banana: :th:

Top colour tomorrow with luck. :th:

Doesn't look like I've done much but this lot took almost 2 days, weathering, decals, finishing off. I'm still unhappy with the red edging on the undercarriage doors, I'm thinking of starting again, watch this space.
Image
The colour coat was a real challenge for me :crazy:
My research tells me USN aircraft late 50's - 80's used a full gloss finish instead of the usual matt finish. A gloss finish is a lot easier to keep them clean and free from saltwater corrosion on carrier operations. I think as paint technology improved it allowed matt and low viz. Anyway the paint it's self was fine but bits of fluff etc :wall: :wall: :wall: :wall: After 3 small area rub downs and touch up's I think I'm there :th:

Just the underside top coat to go now :th:

And started on the gloss varnish ready for decaling and weathering, I use X-22 with levelling thinner which is a little hot and can make the surface soft until it's flashed off, about 15mins. It slid off the stand and

Decals are on :banana: Not bad quality certainly way better than Kitty Hawk, but the surface finish isn't great, some proved to be a challenge in application :crazy:

Nice work.

Love the older schemes. So much more interesting the painfully dirty looking low viz modern stuff.
Its been tried and tested, it works! So don't blame the system if you're no good. :doh:

Ok, I've been working at this every day for a least a 4 hrs a day :crazy:

The fluff/hair/fibres issue returned after panel lining and sealing, I had to rub a lot of areas down to remove them :wall: :wall: I'm really getting P.......off with it, I just can't seem to stop them as soon as it's gloss or clear coat it's like a magnet :crazy: :wall:

After 3 rub downs and re-coats it's as good as it's going to get, if you look with a magnifier you'll see the bits in the semi gloss varnish :wall: I was going for used but not too weathered as these jets, didn't seem to suffer all the damage WW2 aircraft did, mainly I think as their finish was of a higher standard.
Image
Image
I then noticed this on the front wing root :wtf: :wall:
Image
So more repairs :crazy: :wall: :wall: :crazy:
Image
Just the panel lines to redo.

I can then start the weathering and full assembly ;)

Fantastic looking aircraft. I feel I can't call it a model cause that would detract from it. Very nice , but the canopy masks are still on...damn it's going to look even better shortly :th: :th: :th: :th: :cheers2:

I've been beavering away on this build had a few more issues, this time with the weapons load :wall: I should have spotted these but didn't dry fit, before painting expecting no real fit issues.............wrong :wall:
The holes are two different sizes and on the drop tank in the wrong place :wtf: :crazy:
