Reports that Iran’s Supreme Leader Ayatollah Ali Khamenei was killed in a coordinated U.S.–Israel strike on February 28 have drawn global attention not only for the geopolitical shock but also for the weapon allegedly used in the operation: the Blue Sparrow missile.

The missile, part of Israel’s Sparrow family of air-launched ballistic systems, is often described as a “missile from space” because of its unusual flight path. According to multiple reports, Israeli forces used the Blue Sparrow to hit a heavily secured compound where Khamenei and senior Iranian officials were meeting.

If accurate, the strike represents one of the most sophisticated targeted operations in modern military history, combining long-term intelligence gathering with advanced missile technology designed to evade air defenses.

Below is a closer look at the Blue Sparrow missile, how it works, and how intelligence agencies reportedly located Khamenei before the strike.

What Is the Blue Sparrow Missile?

The Blue Sparrow missile is a medium-range air-launched ballistic missile developed by Israel for high-speed precision strikes and missile defense testing.

It is produced by Rafael Advanced Defense Systems, one of Israel’s leading defense contractors, and was initially developed by Israel’s Armament Development Authority.

Key specifications

• Length: 6.51 meters (21.4 feet)
• Weight: Around 1,900 kg
• Range: Approximately 2,000 kilometers (1,240 miles)
• Launch platform: Fighter aircraft
• Flight type: Ballistic trajectory with a re-entry vehicle

Unlike conventional cruise missiles, the Blue Sparrow travels in a high ballistic arc, climbing toward the edge of Earth’s atmosphere before descending at extreme speed toward its target.

This trajectory is why the system is sometimes referred to as a “missile from space.”

Why the Blue Sparrow Is Called a “Missile From Space”

The nickname comes from the missile’s near-space ballistic trajectory.

How the flight path works

1. Air launch: The missile is released from a fighter jet at high altitude.
2. Ballistic climb: It rapidly climbs toward the upper atmosphere.
3. Re-entry phase: A re-entry vehicle separates and begins descending.
4. High-speed strike: The payload hits the target at extremely high velocity.

Because the missile approaches from above at high speed, it can be difficult for traditional air-defense systems to intercept.

Military analysts often compare this attack profile to ballistic missile re-entry vehicles, which are designed to overwhelm interception systems.

The Sparrow Missile Family Explained

The Blue Sparrow is one member of a broader set of Israeli missile systems designed primarily for testing and simulating ballistic missile threats.

Major Sparrow variants

1. Black Sparrow

• Shorter-range system
• Often used in missile defense exercises
• Reportedly used to destroy Iranian surface-to-air missile batteries during the ongoing conflict

2. Silver Sparrow

• A larger and more advanced missile target system
• Used in tests of Israel’s Arrow missile defense system

3. Blue Sparrow

• Medium-range air-launched ballistic system
• Capable of reaching targets up to 2,000 km away

Together, these systems help Israel simulate threats similar to those posed by regional ballistic missiles, allowing air defense systems to train against realistic attack profiles.

How Intelligence Agencies Located Khamenei

The missile strike was only the final step in what reports describe as a years-long intelligence operation.

According to reporting from The New York Times and regional outlets, the operation relied on persistent surveillance and a key intelligence breakthrough.

Months of monitoring

U.S. and Israeli intelligence agencies—particularly the CIA—reportedly spent months studying:

• Khamenei’s daily routines
• His travel patterns
• The security protocols surrounding his movement
• Locations where he might appear during a crisis

Following escalating tensions with Israel, Khamenei reportedly spent extended periods in underground bunkers to avoid assassination attempts.

The critical intelligence break

Intelligence officials reportedly learned that Khamenei would attend an unusually high-level meeting on the morning of February 28.

The meeting was expected to include:

• Senior Iranian political officials
• High-ranking military commanders
• Strategic advisers

Because such gatherings are rare—and present multiple leadership targets in one location—the intelligence triggered urgent operational planning.

Final confirmation before the strike

Before launching the attack, surveillance systems reportedly confirmed Khamenei’s presence at the compound using advanced tracking and intelligence tools.

These tools may have included:

• Satellite imaging
• Signals intelligence
• Human intelligence sources
• Real-time monitoring of movement around the facility

Once analysts confirmed the location, planners reportedly moved quickly to ensure the strike occurred while the leadership meeting was still underway.

Why the Blue Sparrow Was Likely Chosen for the Strike

Targeted strikes against heavily fortified compounds require weapons that combine speed, accuracy, and the ability to evade defences.

The Blue Sparrow offers several advantages.

1. High-altitude trajectory

Approaching from near-space allows the missile to bypass some radar systems optimised for lower-altitude threats.

2. Extreme terminal speed

The re-entry vehicle descends at very high velocity, reducing the window for interception.

3. Precision targeting

Air-launched systems can be deployed from flexible positions, allowing planners to adjust launch points based on operational needs.

4. Long operational range

With a range of roughly 2,000 km, aircraft can launch the missile far outside the reach of many air defense systems.

Iran’s Response to Khamenei’s Death

Following reports of Khamenei’s assassination, Iran launched retaliatory strikes against Israeli and U.S. targets.

According to regional reports, Iranian missiles targeted:

• Israeli military infrastructure
• U.S. military bases in Gulf countries
• Installations in the United Arab Emirates

The strikes signal a potentially dangerous escalation that could widen the conflict across the Middle East.

Why the Strike Matters Geopolitically

The killing of a sitting supreme leader—if confirmed—would represent an extraordinary escalation in modern state conflict.

Several factors make the event significant:

Leadership vacuum

Iran’s Supreme Leader holds ultimate political and military authority. His death could trigger:

• Internal power struggles
• Rapid leadership succession debates
• Potential instability within Iran’s political system

Regional escalation risk

Iran maintains influence through allied groups across the region. Retaliation could occur through:

• Direct missile strikes
• Proxy attacks
• Cyber operations

Strategic precedent

A successful targeted strike on such a high-profile leader could reshape how advanced intelligence and precision weapons are used in future conflicts.

TL;DR

• Reports say Israel used the Blue Sparrow missile to kill Iran’s Supreme Leader Ayatollah Ali Khamenei on February 28.
• The missile is an air-launched ballistic system with a range of about 2,000 km.
• It is nicknamed the “missile from space” because it climbs toward the edge of Earth’s atmosphere before descending at high speed.
• U.S. and Israeli intelligence reportedly tracked Khamenei for months before identifying a rare leadership meeting where he was present.
• Iran responded with retaliatory missile strikes on Israeli and U.S. targets in the region.
