Source-derived summary

The S-75 (Russian: С-75; NATO reporting name SA-2 Guideline) is a Soviet-designed, high-altitude air defence system. It is built around a surface-to-air missile with command guidance. Following its first deployment in 1957 it became one of the most widely deployed air defence systems in history. It was produced in the People's Republic of China under the names HQ-1 (under licence) and HQ-2 (modified, named FT-2000A). Egyptian engineers produced a reverse-engineered S-75 with the name Tayir-as-Sabah.

The S-75 system scored the first destruction of an enemy aircraft by a surface-to-air missile with the shootdown of a Taiwanese Martin RB-57D Canberra over China on 7 October 1959, which was hit by a salvo of three V-750 (1D) missiles at an altitude of 20 km (66,000 ft). This success was credited to Chinese fighter aircraft at the time to keep the S-75 program secret.

This system first gained international fame when an S-75 battery, using the newer, longer-range, higher-altitude V-750VN (13D) missile was deployed in the 1960 U-2 incident, when it shot down the U-2 of Francis Gary Powers overflying the Soviet Union on May 1, 1960. The system was also deployed in Cuba during the Cuban Missile Crisis, when it shot down another U-2 (piloted by Rudolf Anderson) overflying Cuba on October 27, 1962, almost precipitating a nuclear war. North Vietnamese forces would use the S-75 extensively during the Vietnam War against US air power, such as in the defence of Hanoi and Haiphong.

Editorial summary

This brief starts where responsible research should: with the source description of “S-75 Dvina” as surface-to-air missile system. Everything that follows is an evidence route, not borrowed authority.

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—1957, 1959, 1960, 1962—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where S-75, Dvina and surface-to-air can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as surface-to-air missile system. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q163186. The Library of Congress control number is sh2011003445. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1957, 1959, 1960 and 1962.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
