Source-derived summary

The Long March 2F (LM-2F; Chinese: 长征二号F火箭), also known as Chang Zheng 2F (CZ-2F), is a Chinese human-rated two-stage hypergolic-fuelled medium-lift launch vehicle, part of the Long March 2 rocket family. Launching the Shenzhou spacecraft on all 22 flights of the Shenzhou program, it is one of three in-service orbital rockets worldwide to have launched multiple crews, alongside Russia's Soyuz-2 and the US Falcon 9.

The Long March 2F is a two-stage version of the Long March 2E rocket, which in turn was based on the Long March 2C launch vehicle. The entire family is based on the Soviet R-2. The rocket is entirely fuelled by the hypergolic mixture of unsymmetrical dimethylhydrazine and dinitrogen tetroxide. The first stage is powered by four YF-20B engines, as well as four boosters each with one such engine; the second stage uses one YF-24 engine.

It is launched from complex SLS at the Jiuquan Satellite Launch Center. The Long March 2F made its maiden flight on 19 November 1999, with the Shenzhou 1 spacecraft. After the flight of Shenzhou 3, Chinese President Jiang Zemin named the rocket Shenjian (神箭, lit. 'Divine Arrow').

On 15 October 2003, a Long March 2F launched Shenzhou 5, China's maiden crewed mission and achieved its first human spaceflight.

Editorial summary

Begin with the source’s own compact description: “Long March 2F” is chinese launch vehicle. The dossier treats that line as a proposition to test through Long, March and Chinese, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1999, 2003—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Long, March and Chinese is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “chinese launch vehicle” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q53710. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1999 and 2003.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
