I think American tankers on Okinawa might differ with the article in regard to the notion of its "diminishing effectiveness". It wasn't a great gun by any means, but it did remain quite dangerous to the end of the war. One could also wonder about the cause of such a diminishing. After all, it's not as if the United States kept introducing newer and better tank designs into service, especially in the Pacific.-- 172.190.48.224 ( talk) 06:31, 14 July 2012 (UTC)
Could anyone provide some sources on this subject please? Googling this (Japanese) designation only nets me a handful of sites of unclear reliability, which provide some more details on this gun, but don't bother with listing any sources either. The recognized historians on this subject, like Zaloga (in his newest 'Sherman vs. Chi-Ha' book) or Takizawa, definitively state that the development of a new 47mm gun was started as a result of Khalkhin Gol fighting in 1939, so all this appears pretty confusing. -- Saə ( talk) 09:15, 22 October 2012 (UTC)
War Department Special Series No. 19 ''Japanese Infantry Weapons'' December 1943 Section VIII. ANTITANK AND INFANTRY GUNS-Continued. Page 36. MODEL 1 (1941) 47-MM GUN 206 a. General 206 b. How to Identify 206 c. Characteristics 208 d. How to Operate 209 e. Ammunition 209 Page 206 MODEL 1 (1941) 47-MM GUN a. General The Model 1 (1941) 47-mm gun (figs. 133 and 134) is a new gun of modern design. It is an anti-tank and anti-personnel weapon. b. How to Identify The Model 1 (1941) 47-mm gun may be identified by (1) The long barrel, reinforced at the muzzle. (2) The exceptionally long trails. (3) The rubber tires. (4) The marking which is above the breech. This marking, which is read "Ichi ShikiKido Yonjunana Miri Ho" from right to left, means "model mobile 47-mm gun." c. Characteristics The Model 1 (1941) 47-mm gun has a long barrel with a jacket and a hoop, and is heavily reinforced at the muzzle. The breechlock is a horizontal sliding wedge, hand or semiautomatic in operation (fig. 135). The gun is transported with the trails closed, locked with a yoke. This gun is adapted for motor transport only. Its great length and low clearance make it difficult to manhandle except on exceptionally favorable terrain. A wide shield, cut away at the bottom, is provided. Perforated steel disk wheels are fitted with rubber tires. The tread is wide, but ground clearance is low. The low silhouette, wide tread, and long trails should give this gun excellent stability. Preliminary tests indicate a muzzle velocity of 2,700 feet per second. d. How to Operate All of the details on the operation of this gun are not known. It is believed, however, that it may be operated in the same manner as the Model 94 (1934)37-mm gun (par. 35, p. 194). e. Ammunition The rimmed armor-piercing-high-explosive round has a brass case. It is of comparatively large diameter, necked down to take the 47-mm projectile. The projectile has a red tip, a black body, and a white band just in front of the copper rotating band. Specifications for the round are as follows: Length of complete round 15.54 inches. Weight of complete round 6 pounds 6.4 ounces. Maximum diameter of case 2.55 inches. Length of case 11.09 inches Length of projectile 4.45 inches. Weight of projectile 3 pounds 6.4 ounces. Weight of propellant 13.94 ounces. A simple high-explosive round is also reported to be available for use in this weapon.

The combat record section is full of erroneous data. The excerpt about being able to penetrate the M4A6, originally states that the gun was able to penetrate all parts of the tank, EXCEPT the glacis plate. Likewise, no data on the Type 4 solid shot AP penetration survived the war. Shinhoto ( talk) 05:56, 16 May 2021 (UTC)
