Marushin diecast are impressive pieces of of metal. Very little plastic, solid, great panel lines but completely bereft of cockpit detail. They need to be assembled but this as a rule is easily done. Saves on box storage space. Other that the Willow I encountered few snags that were not worked through with very basic modeling skills and a small screwdriver and swiss army knife. The canopies are snap in arrangements but a drop of clear elmers glue holds them in place. Some owners have used 1.48 plastic model cockpit interiors and created astonishing detail to flesh out their Marushins, but I personally have never attempted this. The landing gear is also sparse on detail but not so noticeable. Cannon, machine guns and pitot tubes are metal rods and should be painted. The rods can take a bit of filing down to place within the wings  but Marushins are  worth the effort.  

This particular model is the later Model 22 based on the Shokaku in 1943.  AI-2-236  Some diecast distributors list it as a 1941 variant  but the D3A2 was not available in 1941 at the time of Pearl Harbor.    



The Aichi D3A (Allied code name Val) was a World War II dive bomber produced by the Aichi company in Japan. It was the primary carrier-borne dive bomber in the Imperial Japanese Navy in the early stages of the war.  The Aichi D3A was the first Japanese aircraft to bomb American targets commencing with Pearl Harbor and U.S. bases in the Philippines, such as Clark AFB .  



It was stable but lightly armored—a short burst from heavy machine guns could easily destroy it. Armed with two forward-firing 7.7 mm machine guns, one flexible 7.7 mm machine gun in the rear cockpit, one 550 lb bomb under the fuselage and two 130 lb bombs on wing racks, the Val is perhaps best known for the part it played in the bombing of Pearl Harbor.  They were based on carriers: Kaga, Akagi, Ryujo, Soryu, Hiryu, Shokaku, Zuikaku, Shoho, Zuiho, Chitose, Chiyoda  with the 12th, 14th, 31st, 33rd, 35th, 40th, 541st and 582nd Kokutais.      

Japanese veterans described the "Val" as very stable and easy to fly and land on a carrier. However, the Kinsei engine was slightly prone to leak oil from its cylinders, which sometimes ran across the windshield and obstructed visibility.

Vals sank more Allied warships than any other Axis aircraft, despite being considered obsolescent when the war started.  It was not able to hold as steep a dive as the U.S. Navy’s Dauntless (65 degrees versus over 70 degrees) but pilot skill more than made up the difference, with a hit accuracy of better than 80% against the British carrier Hermes and cruisers Cornwall and Dorsetshire. It is a measure of how badly Japanese pilot skill deteriorated that, by the end of the war, the remaining "Vals" were hitting their targets only 10% of the time.


Aichi Kokuki K.K. (Aichi Aircraft Co Ltd) was Japan's fourth leading manufacturer of aircraft. It was originally founded as the Aichi Tokei Denki K.K. (Aichi Clock and Electric Co Ltd) which began producing seaplanes for the Navy in 1920. The company initially drew heavily on German expertise, particularly from the Heinkel Company.  



During the war years, airframes and engines were manufactured in or near Nagoya. The principal aircraft manufactured by Aichi were the D3A Val, D4Y Judy, E16A Paul, and B7A Grace and the principle engine manufactured was the license-built Daimler-Benz DB 601, known in Japanese service as the Ha-40 or the Atsuta (after the name of the factory.)In late 1944, Aichi responded to the threat of air attack just as their German allies did, by moving airframe production to Ogaki, an underground factory at Seto just east of Nagoya, engine production was relocated to an underground factory southwest of the  Tsu Naval Air Station. From 1941 to 1945, Aichi produced a total of 3627 airframes, of which practically all (3611) were combat aircraft. During the same time period, Aichi produced 1783 aircraft engines.

In mid-1936 the Japanese Navy issued the 11-Shi specification for a monoplane carrier-based dive-bomber to replace the existing D1A biplanes currently in service. Aichi, Nakajima and Mitsubishi all submitted designs, and Aichi and Nakajima were both asked for two prototypes each. Range & speed was to be compatible with the A5M "Claude



The Aichi design started with low-mounted elliptical wings inspired by the Heinkel He 70 Blitz. The fuselage looked quite similar to the Zero, although the entire plane was built stronger to withstand the rigours of dive bombing. It flew slowly enough that the drag from the landing gear was not a serious issue, so fixed gear were used for simplicity. The plane was to be powered by the 710 hp (529 kW) Nakajima Hikari 1 nine-cylinder radial engine.


The first prototype was completed in December 1937, and flight trials began a month later. Initial tests were disappointing. The aircraft was under powered and suffered from directional instability in wide turns, and in tighter turns it tended to snap roll. The dive brakes vibrated heavily when extended at their design speed of 200 knots (370 km/h), and the Navy was already asking for a faster diving speed of 240 knots (440 km/h).

The second aircraft was extensively modified prior to delivery to try to address the problems. Power was increased by replacing the Hikari with the 840 hp (626 kW) Mitsubishi Kinsei 3 in a redesigned cowling, and the vertical tail was enlarged to help with the directional instability. The wings were slightly larger in span and the outer sections of the leading edges had wash-out to combat the snap rolls, and strengthened dive brakes were fitted. These changes cured all of the problems except the directional instability, and it was enough for the Aichi D3A1 to win over the Nakajima D3N1.

As the war progressed, there were instances when the dive bombers were pressed into duty as fighters in the interceptor role, their maneuverability being enough to allow them to survive in this role. In June 1942, an improved version of the D3A powered by a 969 kW (1,300 hp) Kinsei 54 was tested as the Model 12. The extra power reduced range, so the design was further modified with additional fuel tanks to bring the total tankage to 900 L (240 US gal), giving it the range needed to fight effectively over the Solomon Islands. Known to the Navy as the Model 22, it began to replace the Model 11 in front-line units in autumn 1942, and most Model 11s were then sent to training units.

When the Yokosuka D4Y Suisei became available, the D3A2s ended up with land-based units or operating from the smaller carriers, which were too small to handle the fast-landing Suisei. When American forces recaptured the Philippines in 1944, land-based D3A2s took part in the fighting, but were hopelessly outdated and losses were heavy. By then, many D3A1s and D3A2s were operated by training units in Japan, and several were modified with dual controls as Navy Type 99 Bomber Trainer Model 12s (D3A2-K). During the last year of the war, the D3A2s were pressed back into combat for kamikaze missions. It was not a particularly successful kamikaze aircraft, achieving few results for the number of aircraft expended




IJN Shokaku (Japanese: 'Flying Crane'), 1942  Her complement consisted of 15 Mitsubishi A6M2 "Zero" fighters, 27 Aichi D3A2 "Val" dive bombers, and 27 Nakajima B5N2 "Kate" torpedo bombers.

IJN Shokaku (Japanese: 'Flying Crane') was an aircraft carrier of the Imperial Japanese Navy, the lead ship of her class. Along with her sister ship Zuikaku, she took part in several key naval battles during the Pacific War,  Shōkaku joined the Kido Butai ('Mobile Unit/Force', the Combined Fleet's main carrier battle group) and participated in Japan's early wartime naval offensives, including Pearl Harbor and the attack on Rabaul in January 1942.  In the Indian Ocean raids of March–April 1942, aircraft from Shokaku, attacked Colombo, Ceylon on 5 April, sinking two ships in harbor and severely damaging support facilities. The task force also found and sank two Royal Navy heavy cruisers, (HMS Cornwall and Dorsetshire), on the same day, as well as the aircraft carrier HMS Hermes on 9 April off Batticaloa.   Shokaku's aircraft helped sink the American aircraft carrier USS Lexington during the Battle of the Coral Sea but was herself severely damaged on 8 May 1942 by dive bombers from USS Yorktown and Lexington.




On the journey back for repairs, the carrier shipped so much water through her damaged bow she nearly capsized in heavy seas, maintaining a high rate of speed in order to avoid a cordon of American submarines out hunting for her. She arrived at Kure on 17 May 1942.  On 14 July, she was formally reassigned to Striking Force, 3rd Fleet, Carrier Division 1.  The time required for repairs, combined with the aircraft and experienced aircrew and maintenance crew  losses incurred by her and Zuikaku, kept both carriers from participating in the Battle of Midway.
Following her return to front-line duty, both Shokaku and her sister-ship Zuikaku, with the addition of the light carrier Zuiho;, were designated as First Carrier Division and took part in two further battles in 1942: the Battle of the Eastern Solomons,



26 October 1942:
Carrier Battle of Santa Cruz (IJN - "Naval Battle of the South Pacific"):  

- 0050 A PBY makes a surprise attack on Kido Butai, dropping four 500 lb bombs Nagumo orders the second wave planes in the hangars degassed and disarmed fearful of another Midway disaster and for Kido Butai to reverse course north at 0130 for the time being.

- 0450 Lookouts having detected enemy scout bombers, expecting attack, SHOKAKU is forced to launch immediately nine fighters including four detached from the strike to join the three already on CAP duty.

- 0458 Nagumo receives sighting report from a SHOKAKU search plane of one Saratoga-class CV and 15 other ships bearing 125 degrees, distance 210 miles from Kido Butai. He orders immediate launch of the spotted strike, and also sends SHOKAKU's fast scout plane aloft to double-check the sighting.

- 0510 SHOKAKU launches 4 fighters and 20 torpedo planes under command of Lt. Murata Shigeharu. Nagumo recovers some CAP, then orders the armed second-wave raised from the hangars to the flight decks for launch.  



- 0540 Kido Butai is suddenly bombed by two ENTERPRISE search bombers which attack ZUIHO then 8,000 meters abeam of SHOKAKU's port side. They score a remarkably effective 500 pound bomb hit on ZUIHO's fantail which makes her unable to recover aircraft. Fearing a repeat of the Midway disaster, the Japanese expedite launch preparations for the second wave; fuel carts being simply rolled overboard to lessen danger while even aviators assist the deck personnel in loading torpedoes faster.



- 0610 SHOKAKU launches 3 CAP and her second strike wave of 5 fighters and 20 Val dive-bombers under command of Lt. Seki Mamoru.  
- 0640 SHOKAKU's radar detects inbound enemy strike, 78 miles away. A CAP of twenty-three fighters is readied over the carriers.  

- 0727 Ten SBDs from USS HORNET attack SHOKAKU  Though three or four of the first dropped miss, nearly all of the remainder 1,000 pound bombs hit. She is heavily damaged.  Large fires are started, and the flight deck is completely buckled, and shattered. The center elevator is folded and ruined. 12.7 cm AA guns No.6 and No.8 were completely destroyed and nearly all those crews killed.. However, the strength deck holds and there is no significant damage below waterline and SHOKAKU is able to maintain 30 knots.  Nagumo's shift north had succeeded and all the rest of the American strike had missed Kido Butai and been drawn to attack the Advance Force of Kondo's two battleships and cruisers    




CarDiv 1's aircraft attacked TF-17 , crippling HORNET with three bomb hits and two suicide crashes, one of whom was Lt. Seki Mamoru.  In a 15-minute period, Hornet was hit by three bombs from Aichi D3A "Val" dive bombers. One "Val", after being heavily damaged by anti-aircraft fire while approaching Hornet, crashed into the carrier's island, killing seven men and spreading burning Avgas over the deck.   the second crashed into the port forward gun gallery  



Meanwhile, a flight of Nakajima B5N "Kate" torpedo planes attacked Hornet and scored two hits, which seriously damaged the electrical systems and engines. As the carrier came to a halt, another damaged "Val" deliberately crashed into Hornet's port side near the bow and two torpedo hits  that left her dead in the water and severely damaging ENTERPRISE with two bomb hits, but the nimble U.S. carrier avoided all subsequent torpedo attacks.




- At 0940 SHOKAKU and ZUIHO retire northwest at 28 knots.  ZUIKAKU sets about landing "orphaned" aircraft at 0940. Of these, 5  SHOKAKU torpedo planes and 1 fighter are unable to do so, and ditch.  By the time she left the battle, SHOKAKU had only 4 fighters and 1 torpedo plane left aboard, all the Vals and many of her crack aircrews and maintenance hanger were lost.  US sub forces track Shokuko  identified by code breakers as Wounded bear but can not catch her  


The IJN  damaged USS Enterprise crippled USS Hornet (Hornet was abandoned and later sunk by Japanese destroyers Makigumo and Akigumo), but Shokaku was in turn damaged by dive-bombers of Enterprise, which therefore prevented the bombardment of nearby Henderson Field, and once again kept her out of action for months, leaving other Japanese defensive operations in the Pacific lacking sufficient airpower.

A Japanese "Val" dive bomber, believed to be piloted by Yoshihiro Iida, is shot down by anti-aircraft fire directly over Enterprise  



The bomb was dropped by a Japanese Aichi D3A1 ‘Val’ dive bomber piloted by Kazumi Horie who died in the attack. According to the original photo caption in the US Navy's archives, this explosion killed the photographer, Photographer's Mate 3rd Class Robert F. Read. This image, however, was actually taken by Photographer's Mate 2nd Class Marion Riley, who was operating a motion picture camera from the aft end of the ship's island, above the flight deck and who survived the battle although his photographic equipment was damaged.




After several months of repairs and training, Shokaku, now under the command of Captain Matsubara Hiroshi, was assigned in May 1943 to a counterattack against the Aleutian Islands, but the operation was cancelled after the Allied victory at Attu.  For the rest of 1943, she was based at Truk, Here many remaining experienced air crew are transferred, fed into the cauldron that has become Rabaul. Shokaku then returned to Japan for maintenance late in the year. The Val livery Marushin produced was based on the Shokaku in June of 1943.  



Shokaku and her air group met their end at the battle of the Phillipine sea from torpedoes fired by American submarine Cavalla.

Aichi D3A2 “Val” under reconstruction at planes of Fame Chino CA,.

2009 saw progress in the long term restoration of the Japanese Aichi D3A2 “Val” dive bomber.  Sections 3, 4, and 5 of the cockpit canopy were completed and a new bulkhead for the tail section was completed.  New attachment fittings for the rudder and vertical stabilizer were also machined and installed plus many ribs were redone.  



Replicas of the B5N2s were made from U.S. North American T-6 Texan trainers, and Aichi D3A dive bombers were created using BT-13 Valiant training aircraft, which were modified to represent Japanese aircraft for the movie Tora! Tora! Tora!, and have been used in a number of movies and airshows since to depict the aircraft.



A total of 1495 D3A were manufactured as follows

Early production D3A1s had a 1000 hp (746 kW) Kinsei 43 engine.
The D3A2 had a 1300 hp (969 kW) Kinsei 54 engine, which increased its maximum speed to 267 mph (430 km/h) at 20,000 feet (6100 meters).
Aichi Kokuki K.K., at the Funakata, Nagoya plant built
470 D3A1 Model 11 production aircraft (12/39 – 8/42)
1 D3A2 Model 12 prototype (6/42)
815 D3A2 Model 22 production aircraft (8/42 – 6/44
Showa Hikoki Kogyo K.K. in Tokyo built

PostSubject: My new VAL and my old Shokaku   Tue Feb 21 2017, 11:22

My Marushin VAL finally arrived from Japan. The reason I popped the big bucks for it was because I thought it'd look cool sitting next to my 1/700 scale Shokaku. I think I was 13 or 14 when I built this and have managed to keep it ever since (39 years do the math if you want lol). I also still have the Musashi. I don't have this big thing for the Japanese navy or anything its just that a friend of mine and I built a ton of 1/700 waterline ships. At one point I probably had twenty or so. I picked the Japanese because you don't get to see as many pictures of them and curiosity about the enemy I suppose. While maybe not the best modeling job I still can't believe a 14 yr old kid hand painted those planes. Here are a few pictures. I was having fun putting a 1/700 VAL next to my 1/48 one. If anyone wants to chime in and help me remember which aircraft those white nosed fighters are that appear to have inline engines. Thanks Kyshu J7W they are Judys.
