People's Liberation Army Strategic Support Force

The People's Liberation Army Strategic Support Force was a service branch of the People's Liberation Army that existed from December 2015 to April 2024.

With an aim to improve the army's ability to fight what China terms "informationized conflicts" and enhance the PLA's power projection capabilities in space and cyberspace, the PLASSF was a force purportedly designed to break stovepipes in the intelligence sharing and coordination departments of the different branches.

On April 19, 2024, the Strategic Support Force was dissolved and split into three independent arms: the People's Liberation Army Aerospace Force, the People's Liberation Army Cyberspace Force and the People's Liberation Army Information Support Force.

History
At the 2015 China Victory Day Parade, the Chinese Communist Party (CCP) general secretary and Central Military Commission (CMC) chairman Xi Jinping announced sweeping reforms to the structure of the Chinese People's Liberation Army (PLA) and the state security apparatus. On 22 December 2015, the Chinese PLA newsletter, Liberation Army Daily, reported that as part of the joint military exercises taking place that same year, strategic and logistical support forces were included in those exercises along with Intelligence and other high-profile units among the Central Military Commission.

On 31 December 2015, the PLA Strategic Support Force held its first annual meeting at the Bayi Building in Beijing. In attendance were the CMC leadership and leaders of the PLA Ground Force and Rocket Force. CMC Chairman Xi Jinping was also in attendance, giving out military flags and instructional speeches, along with CMC Vice Chairmen and CCP Political Department members Fan Changlong and Xu Qiliang. Fan Changlong read out the CMC's orders and decisions issued by Chairman Xi on the formation of the PLA's leadership and forces, while Vice Chairman Xu Qiliang presided over the meeting.

On 1 January 2016, the next day, Yang Yujun of the Chinese Ministry of National Defense issued a statement on the new Strategic Support Force describing it as formed by the "functional integration" of various support forces that are strategic, basic, and supportive. Another expert, Rear Admiral Yin Zhuo of the PLA Navy, noted:

"The major mission of the PLA Strategic Support Force is to give support to the combat operations so that the PLA can gain regional advantages in the space warfare and cyber warfare domains, and to ensure smooth operations."

Specifically, the objectives of the strategic support force were to include:
 * target acquisition
 * reconnaissance
 * undertaking daily navigation operations, space reconnaissance, and management of Beidou satellites
 * undertaking electronic and cyber warfare and countermeasures

Unlike the PLA Rocket Force, the Strategic Support Force is more dedicated to 5th Generation Information Warfare and is structured to engage in the information space, with emphasis on electronic countermeasures, network offense and defense, satellite management, and some of the functions of logistical supply and dispatch. It also responsible for influence operations, cyberwarfare, and electronic warfare.

On 24 July 2019, the government white paper "China's National Defense in a New Era" published by the State Council Information Office stated:

"The strategic support force is a new type of combat force to maintain national security and an important growth point for new combat capabilities, including battlefield environment protection, Information Assurance and Communication Security, Information Security, testing and integrating emerging technologies, among other things." In April 2024, the Strategic Support Force was dissolved in a reorganization.

Organizational structure
The PLASSF leadership and administrative officials were stationed at their headquarters in the Haidian District of Beijing; the functional departments and leadership of the subordinate units were stationed here. The PLASSF oversaw all units responsible for psychological warfare, information warfare, space warfare, cyberwarfare, and electronic warfare operations formerly under the former General Staff Department.

This included the cyber espionage capabilities of the former Third Department, the electronic support measures from the former Fourth Department, and the space-based ISR systems and Aerospace Reconnaissance Bureau and Satellite Main Station, General Political Department, and General Armaments Department, including the launch, telemetry, tracking, and control facilities and research and development organizations.

General Staff Department
The General Staff Department was under the direction of Admiral Li Shangfu, Chief of Staff. His Deputy Chiefs of Staff were Major General Sun Bo and Major General Zhang Minghua. Subordinated to the General Staff Department was the PLASSF Xingcheng "Rehabilitation" Center.

Political Work Department
The Political Work Department was under the direction of Lieutenant General Feng Jianhua. His Deputy Directors were Major General Chen Jinrong and Major General Huang Qiusheng. Subordinated to the Political Department was the Political Bureau.

Disciplinary Inspection Commission
Also called the PLASSF Supervisory Commission, the Disciplinary Inspection Commission was led by Lieutenant General Yang Xiaoxiang, Secretary. The role of the Disciplinary Inspection Commission was to conduct surveillance and conduct "disciplinary inspections" on PLASSF members in accordance with Article 68 of the March 2018 "Supervision Law" passed by the 13th National People's Congress. The position of Secretary was originally held by Deputy Political Commissar Lu Jiancheng (2016–2019). Subordinated to the Disciplinary Inspection Commission was the Disciplinary Inspection Service.

Space Systems Department
Stationed at the Haidian District of Beijing, the PLASSF Space Systems Department (SSD) was the consolidation of all PLA's space-based C4ISR systems. As of 2018 it was headed by Lieutenant General Shang Hong, with Lieutenant General Kang Chunyuan acting as political commissar. The Space Systems Department also oversaw all of the space launch bases including:

The base was constructed deep in the mountains and deliberately misnamed as part of the Chinese strategy of "backing, concealment, and dispersion". The site mostly served as a nuclear missile site and as a detachment of Jiuqian until its breakaway in January 1976. The launch center was opened to international commercial launches in the 1990s with its launch of two U.S. Iridium satellites into orbit.
