In the 20 18 and 10 issues, Weapons magazine published a textual research on the appearance changes of the first generation Nanchang warship of the Chinese People's Navy (formerly known as the Wuzhi gunboat of the Japanese invaders, namely the Jiang Navy Changzhi warship).

(1) Uji gunboat, as a bridge-type No.2 ship, was completed in April of 194 1. Compared with the first bridge, the armament of the ship has indeed increased slightly, but the so-called six 7.7 machine guns seem to confuse the number of fixed carrier-based guns with the number of light weapons on board.

194 1 year, the 92-type 7.7 mm machine gun on the Uji ship should be 3-4 boats, and there are 6 96-type 6.5 mm light machine guns and a batch of 38 rifles on board as light weapons. In addition, Yasuo Fukui mentioned that both sides of Uji's bridge were equipped with 15cm mortars, but this has not been confirmed.

"Yuzhi" 194 1 year status: when the ship was built, it was equipped with 10 120mm/antiaircraft gun, 1 identical single-barrel gun, and two 96-type double-mounted 25mm guns.

(2) In the late Pacific War, the Uji gunboat was forced to join the Japanese coastal escort operation. In order to deal with the air and underwater threats of the US military, it is equipped with air-to-air radar, sonar, deep-bomb weapons and single-mounted 96 cannon. By the time 1945 surrendered, the Uji gunboat should have five single-loaded 96 guns, 1 door 94 guns (that is, Y guns) and two deep-loaded delivery rails.

Status of Yuzhi 1945: The bullet-proof armor of the superstructure was removed and replaced with a "bamboo armor" made of three layers of bamboo. The rear mast is equipped with radar, and 1 searchlight and four 92 machine guns are removed, and six 96 single-tube 25mm cannons, two deep-charging cannons and 1 deep-charging cannons are added.

(3) According to the government naval records of 1947 to 1948, the auxiliary guns of Changzhi warship (formerly Yuzhi gunboat) at that time were 7 25mm guns (including combined guns and single guns), and there was no record of 40 guns. The People's Navy recorded the armament of Changzhi warships during the uprising in September, with 1949 as 120mm main guns, 40mm 1 cannon guns and 25mm cannons.

Status of "Changzhi" 1946: 1946 After joining the Kuomintang Navy, it cut off the mast, dismantled the radar, dismantled the "bamboo armor", dismantled four single-tube 25mm guns, dismantled all 92 machine guns, deep-charge guns and launch tracks, and installed two Bofors 40mm single-tube guns.

(4) According to the photos of Changzhi ship after the uprising, we can find the following information: ① Changzhi ship is not without radar, but after removing the 13 electric probe on the back mast, American radar is installed on the main mast; (2) Deep-charge weapons have not been cancelled.

(5) (1) The original ship number of Nanchang Ship was 7 1 1, and it was transferred to the Sixth Fleet at 195 1 year. (2) The repaired auxiliary gun and its replacement with Soviet-made 37 cannon; ③ The first stern flag of the East China Navy (1950) is based on the Bayi Army flag. ④ The early painting of East China Navy is unknown, and it may not be blue-gray in the later period.

Status of Nanchang 1950: 1950 In July, the command ship of the Sixth Fleet of the East China Navy retained all the equipment of the Kuomintang period and changed the painting color, with the ship number of 7 1 1.

(6)① The replacement of Soviet-made 130mm naval guns occurred around 195 1 year; (2) Since the early 1950s, Nanchang Ship has had radar; (3) The modification of the bridge shape of Nanchang Ship took place in the early 1960s.

Status quo of "Nanchang" 196 1 year: 196 1 year, the ship is equipped with two single-tube naval guns of type B 13, seven single-tube 37mm cannon of type 70-K and HO-65438+. Replace the main gun rangefinder and reduce the number of work boats to two, with the ship number 2 10.

(7) 1963 stills of the movie "the story of the boatswain", and the ship number of 8 10 is the temporary number in the play. It can be seen that the bridge of Nanchang ship has been transformed, and some auxiliary guns have been replaced by double 37 naval guns.

(8) Status of "Nanchang" 1968: 1968 was rebuilt again, and the bridge was completely rebuilt, and it was changed into a semi-closed bridge similar to the Type 65 frigate, and a sea search radar was added to the masthead. Demolition of the deep-water bomb transport track, six 70k cannons and two HO- 103 machine guns, and replacement of four 6 1 double-mounted 37mm cannons and two Soviet-made DSHK-4312.7mm machine guns with ship number 53-224.
