The '''GJP-152/48''' ([[Menghean language|Menghean]]: 경(輕) 자주포, ''Gyŏng Jajupo'', "Light Self-Propelled Gun, 152mm, 48 calibers") is a type of self-propelled {{wp|Howitzer#Twentieth_century|howitzer}} designed in the [[Menghe|Socialist Republic of Menghe]]. It consists of a [[GSP-152/48]] gun-howitzer on the chassis of a [[Chŏnsŏ G288]] 6x6 utility truck. Initially designed for use in lightweight motorized units for expeditionary service, it now serves primarily in Menghean Artillery Divisions at the Corps and Army level. It is lighter, faster, and less expensive than the tracked [[JJP-152/48]], but it lacks armor and takes longer to emplace and relocate.
The '''P150G3P Hwasu-po''' ("birch gun") is a type of lightweight {{wp|self-propelled artillery|self-propelled}} {{wp|howitzer}} developed in [[Menghe]]. It consists of a 150mm L/46 howitzer on a 6×6 chassis derived from the [[Samsan S915]] utility truck. Initially designed for use in lightweight expeditionary motorized units, it now serves primarily in corps- and army-level artillery divisions. It is lighter, faster, and cheaper than the tracked [[P150G2P Songsu-po]], but it is also less protected and takes longer to properly emplace.


==Development==
==Development==
The GJP grew out of the design process for the GSP-152/48 gun-howitzer, which was initially designed for a stationary mount. From the beginning, this howitzer was intended as the base for a self-propelled tracked gun, which in turn became the JJP-152/48. Work on the combined GSP-152/48 program began in 1990, not long after the [[Decembrist Revolution]]. In order to achieve greater range and accuracy than the preceding GSP-152/27 howitzer, the new gun was built with a longer 7.31-meter (48-caliber) barrel.
The Hwasu-po developed as an offshoot of the New Howitzer Program which yielded the [[P150G2P Songsu-po]]. In the early 2000s, when development was underway, the [[Menghean Army]] envisioned a pivot to expeditionary operations, so a lightweight and air-transportable self-propelled gun was a necessity. After Menghe did intervene abroad in the [[Ummayan Civil War]], the resulting breakdown in relations with [[Maverica]] led to a new pivot to front-line operations along Menghe's long western border, and the Hwasu-po developed into a cost-effective mobile artillery vehicle.


[[Menghean Army|Menghean People's Army]] High Command issued a request for a lightweight, self-propelled, truck-based version of the new howitzer in 1995. Work on the truck-based project was slow at first, with a prototype submitted for testing in 1999 but no service orders until 2004. Large-scale deliveries began in 2008, but by that time the failure of a major intervention had forced the Menghean military to reconsider its strategic priorities, with a shift back to defensive and counter-offensive goals.
==Description==
The main armament of the Hwasu-po is a PG-150 Type 02 howitzer with a caliber of 150mm and a barrel length of 6,900mm (excluding the removable muzzle brake). This is the same weapon carried by the P150G2P Songsu-po, and it has the same range and performance. The P150G3P's rate of fire is reported to be slightly lower due to the different ammunition stowage layout, though the vehicle does appear to feature a power rammer behind the gun to assist with loading. The gun can elevate up to 55 degrees and traverse 25 degrees to either side.


==Design==
The five crew members - driver, gunner, commander, and two loaders - ride in an armored cab based on that of the [[H12G2B40_Ubak#H12G4B80_Ichung_Ubak|H12G4B80 Ichung Ubak]]. Three crew members sit in the front row of seats, and two sit in the rear row, with fire-control equipment stored in between. The cab is protected against shrapnel and small-arms fire, but it can be defeated by 12.7mm fire at typical combat ranges and it cannot withstand shell impacts within a close distance. As on the H12G4B80, the front right seat has a circular overhead hatch sporting a 12.7mm GCh-75 heavy machine gun, which can be used to defend the vehicle against enemy special forces units or light vehicles.
===Armament===
The GJP-152/48 is the first wheeled SPG to be used in [[Menghe]], with the exception of light truck-based {{wp|Infantry_support_gun|infantry guns}} used during the [[Great Conquest War]]. Its main armament consists of the [[GSP-152/48]] gun-howitzer. When firing, a heavy brace is deployed behind the truck so that recoil force is transferred straight into the ground rather than through the suspension. This is accompanied by a lighter platform which supports the loading crew. Maximum elevation is +70 degrees at any angle. Depression is limited to 15 degrees when firing over the cabin and -5 degrees on either side. Traverse is limited to +/-40 degrees left or right. In trials, it takes about 90 seconds for the vehicle to assume its position, deploy, aim, and fire when moving from a road march.


In order to simplify production and logistics, the GJP-152/48 is compatible with all existing 152mm artillery munitions used by Menghe, Polvokia, and the [[Federation of Soviet Republics|FSR]]. When firing the standard PT-152GP high-explosive shell with full propellant charges, it has a maximum range of about 24.8 kilometers. A new {{wp|Base_bleed|base-bleed}} high explosive shell developed for the gun in 1996 extends this to 28.2 kilometers, though at the cost of a lower explosive payload. The greatest range, 44.3 kilometers, is achieved with a {{wp|Rocket-assisted_projectile|rocket-assisted projectile}}. Other ammunition types include the PT-152DCh, which carries {{wp|SMArt_155|two anti-tank submunitions}}, and the '''Mumohan''', a GPS-guided high-explosive round with a maximum range of 38 kilometers and a {{wp|Circular_error_probable|CEP}} of 4 meters.
The P150G3P Hwasu-po has onboard storage space for 35 rounds, with projectiles stored on the right side and propellant charges stored on the left. It can carry the same range of indirect-fire [[P150G2P_Songsu-po#Ammunition|150mm ammunition]] used by the P150G2P, including cluster munition, illumination, and radio jamming shells, though the gun lacks direct-fire sights and therefore cannot fire HEAT ammunition efficiently. Some reports indicate that P150G3P vehicles are typically armed with extended-range base-bleed ammunition to allow them to operate further from the front lines than the better-protected howitzers.


Because the weapon is manually loaded, the exact rate of fire varies depending on the skill of the crew. In a heavy barrage the expected rate of fire is between 6 and 8 rounds per minute. Rate of fire would be kept at 1 to 2 rounds per minute in a sustained bombardment, though this is less common given the shoot-and-scoot design of the system. A total of 24 shells and their associated propellant charges are carried in metal bins between the cabs and the gun itself. In a typical battery organization, one reload truck is assigned to each gun truck.
Official Menghean defense brochures claim that the P150G3P can enter a firing position in as little as one minute and depart in the same time frame, giving it shoot-and-scoot capability. It appears, however, that this speedy emplacement is only possible when laying the reinforcing trails and spades onto the ground without preparation. Digging small pits to properly seat the spades could add to the emplacement time, especially when firing on hard soil. In either case, the disemplacement time of one minute allows the vehicle to depart soon after finishing its fire mission to avoid {{wp|counter-battery fire}}.


===Chassis===
In 2016 the Menghean Army accepted its first deliveries of upgraded P150G3Ps with full integration into the [[Jinri Common Fire Direction System]]. Unlike the P150G2 system, which was redesignated P150G4 when equipped with the Jinri CFDS, the P150G3 system retains its P150G3 designation and still includes forward observer vehicles in its battalions. This may be because P150G3 systems are typically placed in separate artillery divisions, which may have to support front-line units lacking the Jinri CFDS. The P150G4 system, by contrast, is typically used in regimental or divisional artillery units in 4th Generation divisions, which feature fire direction vehicles in all front-line companies.
Mobility is provided by a [[Chŏnsŏ G288]] multi-purpose offroad utility truck, the same kind that forms the logistical backbone of the Menghean Army. Top speed on a flat, paved surface is just under 80 kilometers per hour, but can be much lower on muddy or rocky ground. Because the entire system weighs only 15.5 tonnes fully loaded, it can be easily transported by ship or by air, and it can cross lightweight bridges. Theoretical travel range is listed as 800 kilometers.


A full crew consists of five members: a driver, a commander, a gun-layer, and two loaders. The driver, commander, and gun-layer are all seated three across in the forward cabin, with the two loaders in a separate compartment mounted further back. Because the gun is automatically elevated and traversed based on input coordinates, the gun-layer can complete his task from within the cabin, though he can also exit the vehicle to aim the gun manually in the case of system failure or emergency direct fire. Both of the loaders have to exit their cabin during combat operation, and stand on a deployed platform behind the vehicle in order to pass shells and charges into the breech. In theory the gun can be operated by three crewmen – the gun-layer and two loaders – but this is reserved for emergencies, or if part of the crew has been incapacitated.
==Variants==
* '''P150G3P''' - Original production variant from 2008.
* '''P150G3P1''' - Improved variant seen in 2016. Equipped with a radar antenna over the gun to measure the velocity and deflection of recently-fired shells and correct subsequent fire.
* '''P152G3P''' - Export variant chambered in [[Letnia]]n 152mm ammunition.
* '''P155G3P''' - Export variant chambered in [[Hallia]]n 155mm ammunition.


No armor is provided, even against splinters and small-arms fire, except for the standard metal skin and frame of the G288. Furthermore, in order to operate the weapon the loaders must stand outside the cabin on a rear platform, exposing them to shrapnel from counter-battery fire. The vehicle also lacks a secondary weapon, though all members of the crew carry assault rifles for self-defense. In some cases GJP crews have been seen wearing light body armor as protection, though this does not appear to be standard-issue among artillery units. An up-armored variant with splinter protection for the cabin and rear compartment was considered in 2012 and again in 2014, but in the end it was decided that this would be incorporated into the heavier GJP-152/56, which is still in early development but will feature a 56-caliber gun in an enclosed turret on an armored 8x8 chassis.

==Service==

At the time of its conception and design, the GJP was intended as an expeditionary weapon, capable of being airlifted (but not air-dropped) for easy deployment abroad. In this role, it would have been placed in artillery units at the Divisional level, replacing heavier tracked SPGs like the [[JJP-152/27]]. By the time large-scale deliveries began in 2010, the strategic aims of the [[Menghean Army]] had shifted, and for a while it seemed that the project could be cancelled entirely.
* {{wp|CAESAR self-propelled howitzer}} ([[Sieuxerr]])


A much-needed revival came in 2012, when it was decided that the GJP would be used to replace the towed howitzers in service with Artillery Divisions at the Corps and Army level. For this role, its production run was restored and even increased. It is expected that several thousand will be in operation by the time the current production run is completed.

In 2011, the GJP project was expanded to include the GJP-155/47, which carries a similar artillery gun designed for 155-millimeter ammunition. This variant is intended primarily for export to nations not using 152mm artillery shells.
 
==Variants==

*'''GJP-155/47''': Export variant with a 155mm caliber for compatibility with foreign munitions.
*'''GJP-152/56''': Experimental testbed carrying the longer GSP-152/56 gun-howitzer. It is expected that the actual platform for the wheeled 152/56 will be an 8x8 chassis, possibly one of an entirely new design.

The P150G3P Hwasu-po ("birch gun") is a type of lightweight self-propelled howitzer developed in Menghe. It consists of a 150mm L/46 howitzer on a 6×6 chassis derived from the Samsan S915 utility truck. Initially designed for use in lightweight expeditionary motorized units, it now serves primarily in corps- and army-level artillery divisions. It is lighter, faster, and cheaper than the tracked P150G2P Songsu-po, but it is also less protected and takes longer to properly emplace.
