Review and details

Afternoon chaps

 

Today’s review is on the XA-38 Grizzly, also known as the destroyer, a fast agile twin engined ground attack plane built and flown by the Beechcraft Company in Kansas and while it never saw combat service, it was widely regarded by those that saw it and flew it as a very well made aircraft from a company that had no real experience in this type of plane.

 

Background

[spoiler]

 

The XA-38 traces its roots back to 1942 where Beechcraft (that had is role and fame is small two man commercial and training aircraft) had been designing a bomber destroying aircraft designated model-28 Destroyer as a private venture. While this variant never became a reality, the US Army expressed an interest in the company converting it to a heavy ground attack aircraft for destroying bunkers and armoured units and submarines it was re-designated the XA-38 Grizzly.

 

Design and testing began in earnest from 1943 onwards and unlike many contemporary attack aircraft Beechcraft went straight for the box marked; “Big Guns” fitting a T15E1 75mm cannon and six 12.7mm machine guns as well as an assortment of bombs or rockets to the aircraft. The 75mm gun was designed around an automatic feed system (T13) and carried 20 rounds in the main magazine of either APHE of HE.

The 12.7mm heavy MG’s were situated in the nose (x2) and a pair in dorsal and ventral mini turrets.

The rest of the aircraft was fairly conventional, it was clearly based around the Beech D18S light transport plane and had a smooth flush body and twin tailed rudder assembly with a length of 51.7 feet and wing span 67.08 feet. Outside maximum width of the fuselage was 56 inches and maximum fuselage height 92 inches.

The overall weight for the twin-engine all-metal mid-wing monoplane was 23,230 pounds with an expected gross weight of 29,900 pounds; however, various combinations of fuel, oil, external bombs, long range fuel tanks could allow the XP-38 to carry a maximum alternate gross weight of 36,332 pounds.

 

The engines chosen for the XA-38 were the (for its size) hugely powerful 18-cylinder Wright R-3350-43 Duplex Cyclone engines that delivered 2440 - 2700hp each giving the XA-38 a top speed of 636kph (some sources vary about exact engine variant and speed but most agree between 600 and 636kph) with a climbs rate of 13m/s or higher, despite the speed and weight it was noted that the XA-38 could land a low speed and on short of rough runways with no difficulties.

The first flight of the prototype took place on May 7th 1944 by the army air corp and lasted until 1945 with results that were marked as outstanding, the aircraft was matched against a P51B and much to the pilots surprise he was unable to keep up with the aircraft and the test pilot reported that its handling and turning were almost identical to the fighter that was monitoring it. On ground tests the 75mm cannon proved to be very effective attacking any tanks of the time from the angles and approach that would have been used in a battlefield scenario.

 

Ultimately the XA-38 was never entered into service, with the War in Germany almost over and the pacific war not requiring a tank buster or bomber hunter the XA-38 could not find an adequate role, the secondary issue was the engines which were used on the B29’s and BTD’s both of which had almost exclusive access resulting in a foreseen production issue. With the USA looking to the future and seeing jet planes being the future the XA-38 program was cancelled after just two models had been built.

 

 

The XA-38 remains one of the few planes in WW2 that although never making it to the main production lines would have the war been longer; it would certainly have seen service and possibly have been a decisive aircraft. It also holds one of the few records for an aircraft produced by a company with almost no experience in the field of heavy fighters, that not only worked first time, but was given a thumbs up from day one with both the company and the engineers receiving the respect and admiration from the pilots and the army testing service. Of the two models flown on was destroyed in the 1940‘s the other remains undiscovered and may well be out there today.

In War thunder

I propose this air act would fit in very well at tier III, as a heavy ground attacker and bomber hunter much like the ME410’s and HS129’s – The US tree does not have many aircraft that fit this role, with people preferring the P47 as a fighter over a tank buster. Its good speed and agility that is equal to many fighters gives the XA-38 a varied and mixed play style. That will suit all players.

 

Able to attack ships, air or ground, it fills a nice role for many fans, and will find a home in either RB hunting tanks or AB battles doing a variety of roles. Unlike many X planes it was built and there are enough technical details out there to assist developers in making this plane.

The Grizzly has been suggested previously, but as always, your posts bring an abundance of new information to the table. I'll open this for discussion for now, but I believe we will move it up to Documented Suggestions after a while.

having something like this at around 4.7 or 5 BR would be nice to take care of those pesky G5N1/G8N1s. idk if the performance warrants such a BR though. if it can't handle IV aircraft than its not really needed as bombers aren't really a thing in other nations below IV.

Actually looks very impressive performance wise considering the heavy armament.

Apparently it performed excellently in trials. It was a top notch aircraft...

 

...that used the same engines as the B-29.

 

So, it got the cut.

Mmmm, hugely powerful twin-engine, aircraft carrying a massive gun and loaded to bear with bombs and rockets - the A-10's great-granddaddy :) WANT!!!

There's no two ways about it - this would be a killer choice in Combined Forces.

Well written and thought out suggestion and I enjoy seeing lesser known aircraft in game. Would support it, although not sure if normal tree or premium tree due to it never getting rid of the "X" designator ;-)

 

Best regards,

Hmm, this suggestion has been buried a bit for some time now. I'm glad for the revive, this aircraft would still make a viable addition. :yes:

The prototype status is a bit unfortunate, but the Grizzly would definitely have a useful role to play.

Yeah I know, I was about to suggest it again but I saw this post so I just posted here rather than repost.

 

Yeah its unfortunate considering it was a very viable plane, if it hadn't of been for the push of B-29 production we could have seen a lot more of them.

 

Even if it comes as a premium I would still like that autoloaded 75mm :yes:

Are you trying to challenge german duck ? 8)s

 

Looks great

 

Fact is it will better than the duck in terms of its overall stats, the gun might be slightly better on the duck but this can carry rockets and bombs and has turrets.
