What was the principal strategic objective motivating the development of the Myasishchev M-4 Molot bomber?
Answer: True
The primary strategic objective behind the development of the Myasishchev M-4 Molot was to equip Soviet Long Range Aviation with a bomber capable of intercontinental strikes against targets located within North America. This capability was central to the Soviet Union's Cold War strategy of projecting strategic power against the United States.
Following World War II, the Soviet Union's initial strategy for a long-range bomber involved developing the advanced jet-powered M-4 directly.
Answer: False
Following World War II, the Soviet Union's initial strategy for a long-range bomber involved reverse-engineering the American B-29 Superfortress to create the Tupolev Tu-4. The M-4 represented a subsequent, more advanced jet-powered design.
The Tupolev Tu-4 was considered a permanent solution for Soviet long-range bombing needs due to its advanced jet engines.
Answer: False
The Tupolev Tu-4 was considered a stop-gap measure, not a permanent solution. It was a piston-engine aircraft derived from the B-29 and lacked the range and speed required for intercontinental strikes against the continental United States, and was vulnerable to jet fighters.
Vladimir Mikhailovich Myasishchev was tasked with developing a strategic long-range bomber to counter Western jet bomber advancements.
Answer: True
Vladimir Mikhailovich Myasishchev was indeed tasked in 1951 with the development of a strategic long-range bomber (SDB) to counter the perceived threat posed by advancements in Western jet bomber technology.
The internal designation 'Project 25' was used by Myasishchev for the development of the Tupolev Tu-4 bomber.
Answer: False
The internal designation 'Project 25' was associated with Myasishchev's development program for the M-4 bomber, not the Tupolev Tu-4.
What was the primary strategic objective driving the development of the Myasishchev M-4 Molot bomber?
Answer: To enable Soviet Long Range Aviation to reach targets in North America.
The principal strategic objective driving the development of the Myasishchev M-4 Molot was to equip Soviet Long Range Aviation with a bomber capable of intercontinental strikes against targets located within North America. This capability was central to the Soviet Union's Cold War strategy of projecting strategic power against the United States.
What aircraft served as a stop-gap strategic bomber for the Soviet Union after World War II while a jet bomber was developed?
Answer: Tupolev Tu-4 Bull
Following World War II, the Soviet Union initially prioritized developing a long-range strategic bomber by reverse-engineering the American B-29 Superfortress to create the Tupolev Tu-4. This aircraft served as a stop-gap solution while a more advanced jet bomber, the M-4, was under development.
Why was the Tupolev Tu-4 considered only a temporary solution for Soviet long-range bombing needs?
Answer: Its operational range was significantly shorter than required.
The Tupolev Tu-4 was considered a temporary solution because, unlike American bombers that could operate from bases near the USSR, it lacked the range to reach the continental United States. Furthermore, experiences in the Korean War showed that piston-engine bombers were highly vulnerable to jet fighter interception.
Vladimir Mikhailovich Myasishchev's primary directive was to design what type of aircraft?
Answer: A strategic long-range bomber (SDB)
Vladimir Mikhailovich Myasishchev was tasked by the Soviet Union in the spring of 1951 to construct a *strategichesky dalny bombardirovshchik* (SDB), or strategic long-range bomber, to counter advancements in Western jet bombers.
Which of the following United States bombers is mentioned as comparable to the M-4 in the 'See also' section?
Answer: Boeing B-52 Stratofortress
The Boeing B-52 Stratofortress is mentioned in the 'See also' section as a comparable strategic bomber from the United States, alongside the Convair YB-60.
What does the designation SDB represent in the context of the M-4's development?
Answer: Strategic Long-Range Bomber (*strategichesky dalny bombardirovshchik*)
SDB stands for *strategichesky dalny bombardirovshchik*, a Russian term that translates to 'strategic long-range bomber.' This designation was used by the Soviet government for the program that produced the M-4.
What was the official United States Air Force (USAF) reporting name assigned to the Myasishchev M-4 bomber?

The maximum takeoff weight specified for the Myasishchev M-4 bomber was approximately 181,500 kg (400,139 lb).
Which NATO reporting name was assigned to the improved 3M variant of the bomber?
Answer: Bison-B
The NATO reporting name 'Bison-B' was assigned to the improved 3M variant of the Myasishchev bomber, distinguishing it from the earlier 'Bison-A' designation for the original M-4 model.
The M-4 successfully met its specified range target of 12,000 km during operational flights.
Answer: False
The M-4's actual operational range of approximately 9,500 km fell short of its specified target of 12,000 km, necessitating investigations into inflight refueling capabilities.
Inflight refueling (IFR) investigations for the M-4 began in 1955 due to concerns about its range limitations.
Answer: True
Investigations into inflight refueling (IFR) for the M-4 commenced in 1955, directly addressing the aircraft's demonstrated shortfall in operational range compared to its design requirements.
In 1959, the 3M variant set world records for carrying heavy payloads to significant altitudes.

The public display of M-4 aircraft on May Day 1954 led the United States to believe the Soviets were behind in jet bomber technology.
Answer: False
The public display of M-4 aircraft on May Day 1954 caused considerable surprise and concern in the United States, fueling fears of a Soviet 'bomber gap.' This led to an acceleration of U.S. bomber production, rather than a belief in Soviet inferiority.
The M-4's first public appearance was at the 1955 Paris Air Show, surprising Western observers.
Answer: False
The M-4's first public appearance occurred earlier, during the May Day parade in Red Square on May 1, 1954, which indeed surprised Western observers.
The 'bomber gap' scare of the mid-1950s was primarily caused by accurate Soviet disclosures of their bomber fleet size.
Answer: False
The 'bomber gap' scare was largely fueled by overestimated threat assessments from intelligence agencies, particularly the CIA, which were influenced by Soviet propaganda displays like the M-4 flyby, rather than accurate Soviet disclosures.
Western intelligence agencies accurately assessed the M-4's capabilities from its introduction, recognizing its limitations early on.
Answer: False
Western intelligence agencies significantly overestimated the capabilities of the M-4 and its variants for an extended period, often mistaking the improved 3M for the original M-4, which persisted until the early 1960s.
The public display of M-4 aircraft on May Day 1954 led the United States to:
Answer: Accelerate its own bomber production, fearing a 'bomber gap'.
The public display of M-4 aircraft on May Day 1954 caused considerable surprise and concern in the United States, fueling fears of a Soviet 'bomber gap.' This led to an acceleration of U.S. bomber production, rather than a belief in Soviet inferiority.
The surprise appearance of the M-4 at the May Day 1954 parade in Red Square primarily caused the West to:
Answer: Believe the Soviet Union possessed a significant strategic bomber threat.
The surprise appearance of the M-4 during the May Day 1954 parade in Red Square led Western observers to believe the Soviet Union possessed a significant and advanced strategic bomber capability, contributing to fears of a 'bomber gap'.
What factor significantly contributed to the US 'bomber gap' scare in the mid-1950s?
Answer: Overestimated threat assessments by the CIA based partly on propaganda displays.
The 'bomber gap' scare was largely fueled by overestimated threat assessments from intelligence agencies, particularly the CIA, which were influenced by Soviet propaganda displays like the M-4 flyby, rather than accurate Soviet disclosures.
The Myasishchev M-4 and 3M bombers were frequently deployed in combat missions during the Cold War.
