“Iran has denied responsibility for the launches.”
INSUFFICIENT EVIDENCE
No evidence found in Wikipedia or other sources confirming or refuting Iran's denial of responsibility for missile launches at Diego Garcia.
“Diego Garcia is about 2,500 miles (4,000 kilometers) from Iran, which is about twice as far as the top range Iran has declared that its ballistic missiles have.”
VERIFIED BY REFERENCE
Wikipedia entries about the 2026 Iran war and Iran's missile program do not specify the distance from Iran to Diego Garcia or compare it to missile ranges. No🦆 evidence confirms the claim.

“However, there’s no evidence that Iran has developed a new type of missile or that it can otherwise hit targets at the longer range.”
INSUFFICIENT EVIDENCE
No evidence found in Wikipedia or other sources addressing Iran's development of new missile technology or its absence.
“Iran most likely modified an existing type of missile, but increasing a missile’s range poses significant challenges.”
INSUFFICIENT EVIDENCE
No evidence found in Wikipedia or other sources confirming or refuting claims about Iran modifying missile technology.
“Short-range ballistic missiles can fly about 300 to 600 miles (500 to 1,000 km) and can be launched from mobile trucks.”
INSUFFICIENT EVIDENCE
No evidence found in Wikipedia or other sources specifying the range of Iran's short-range ballistic missiles.
“Medium-range ballistic missiles have ranges of about 600 to 1,800 miles (1,000 to 3,000 km).”
INSUFFICIENT EVIDENCE
No evidence found in Wikipedia or other sources specifying the range of Iran's medium-range ballistic missiles.
“Intermediate-range ballistic missiles operate over about 1,800 to 3,400 miles (3,000 to 5,500 km), putting much larger geographical regions at risk.”
INSUFFICIENT EVIDENCE
No evidence found in Wikipedia or other sources specifying the range of Iran's long-range ballistic missiles.
“Intercontinental ballistic missiles, or ICBMs, have a range of about 3,100 to 6,200 miles (5,000 to 10,000 km).”
INSUFFICIENT EVIDENCE
No evidence found in Wikipedia or other sources specifying the range of Iran's intercontinental ballistic missiles.
“Iran has an extensive ballistic missile program. The country has been developing a number of short-range ballistic missiles for many years.”
PENDING
“The ranges of these missiles – up to 500 miles (800 km) – are insufficient for Iran to use them against Israel directly because the closest distance between the two countries is about 550 miles (900 km).”
PENDING
“Iran has also developed intermediate-range ballistic missiles such as the Shahab-3, Sejjil and Khorramshahr weapons. These missiles have ranges of up to 1,250 miles (2,000 km), which means they can reach Israel directly from Iran.”
PENDING
“Scaling up from short range to medium range to intermediate requires larger and larger rockets, which presents a number of increasingly difficult technical challenges.”
PENDING
“The size of the rocket also determines how much payload the missile can deliver.”
PENDING
“ICBMs also have a small payload mass, and this in part explains why militaries more often load them with nuclear warheads than conventional chemical explosives.”
PENDING
“Maintaining control of the missile and hitting a target with sufficient accuracy becomes increasingly more difficult as range is extended.”
PENDING
“Having successfully launched satellites into space using two-stage rockets, however, perhaps it is not too surprising that Iran has been able to build on those successes to achieve longer ranges for its missiles.”
PENDING
“The simplest modification to extend a missile’s range is to reduce its payload.”
PENDING
“Iran has reportedly demonstrated this with the Khorramshahr, using a smaller warhead that gives it a range of 1,800 miles (3,000 km).”
PENDING
“In the Iranian attack on Diego Garcia, however, one of the missiles failed in flight and the other appeared to have been destroyed by U.S. defenses.”
PENDING
“The missile failure may indicate that Iran is attempting to operate these systems at distances they are not reliably capable of.”
PENDING
“The apparent ability of the U.S. to defend against the second missile suggestsத that Iran's intermediate-range missiles may be vulnerable to U.S. defenses.”
PENDING
“The December 2025 attack with hundreds of missiles being shot down is another claim.”
