Call Me Agent GPT: ChatGPT Breaks Down The Science On Iran's Oct 1st Missile Attacks (Maybe?!)

Is this real?

Elaborate AI hallucinations?

Hang on … did this GPT exchange really happen at all!? (1) 🤔

In the vein of all good writing about the murky worlds of intelligence and defence, we’ll leave those questions hanging in the air.

But for now, give your skepticism a moment to breathe and enjoy GPT-4 Turbo’s attempt to explain some of the mind-wraping science that may have gone into the exoatmospheric war behind Israel and Iran.

(1: This GPT chat, at least, really did happen. We’re waiting on a guy wearing a fedora named Al who says he works for the Ministry of Defence to tell us how much of it is accurate. But this is Israel, so he’s more probably called Moshe and wearing flip-flops…)

Prompt

Hi ChatGPT!

I was wondering if you know about the ballistic missile attack launched by Iran on October 1st?

I know it’s past the cutoff in your training data, but … you can scrape that from the news, right?

Output

On October 1, 2024, Iran launched around 180-200 ballistic missiles targeting Israel, marking one of the most substantial attacks from Iran in the region.

The missile strikes were reportedly part of “Operation True Promise 2” and were directed at military targets, airbases, and some infrastructure near Tel Aviv.

Although Israel’s Iron Dome and other air defenses successfully intercepted many missiles, some impacted locations like Nevatim and Tel Nof airbases.

Civilian areas also went under alert, with injuries reported, though most were minor. Jordan’s and the United States’ defense systems collaborated with Israel to intercept incoming threats

Prompt

That is indeed basically what happened.

I have a few questions for you about the incident.

ChatGPT

Go ahead.

Prompt

Alright then.

Is there any credible data on what missiles Iran launched against Israel?

I believe they were long range ballistic missiles.

Have there been estimates as to which types Iran launched and in which quantities (by which I mean, estimates as to approximately how many of each type)?

Output

Iran launched a substantial number of Fattah-1 and Kheibar Shekan ballistic missiles on October 1, 2024, during an operation known as “True Promise 2.”

This attack targeted Israeli military and intelligence sites, including locations in and around Tel Aviv. Estimates place the number of missiles around 200, likely deployed in two waves, marking it as one of the largest direct strikes from Iran on Israel.

The Fattah-1 and Kheibar Shekan missiles are advanced models capable of reaching Israel within minutes, posing interception challenges due to their speed and accuracy.

The Kheibar Shekan is particularly significant, as it is designed for longer-range targets and complex flight path.

Prompt

Do me a tiny favor, ChatGPT?

I love you dearly, but be a tiny bit more concise in your responses!

I know the background details.

Just summarise the facts, please.

Output

Iran launched around 200 ballistic missiles on October 1, 2024, including advanced Fattah-1 and Kheibar Shekan models, aiming for Israeli military and intelligence sites.

The missiles were launched in two waves, with many intercepted by Israel’s defenses in collaboration with U.S. systems.

Damage was minimal but targeted Nevatim and Tel Nof airbases

Prompt

Much better.

Can you provide some basic parameters about each of those missiles?

Range, when they were introduced into service, how many Iran is speculated to possess, flight range, max altitude and speed.

Could you give me all those datapoints in a matrix layout please?

Accuracy Disclaimer ⚠️

Due to budgetary constraints, this blog has been unable to retain the services of anybody even remotely qualified to adjudicate on whether any of the subsequent information is in any way credible. Treat it with the same suspicion as something you overheard from a guy on the train (okay, maybe a tiny bit more)

Output

Here’s a summary of the specifications for Iran’s Fattah-1 and Kheibar Shekan missiles based on current data:

• Fattah-1 is Iran’s first hypersonic ballistic missile, maneuverable in its reentry phase, which complicates interception. It can travel up to Mach 12, covering 1,400 km in under 12 minutes.
• Kheibar Shekan is a medium-range ballistic missile optimized for precision strikes, with an approximate speed between Mach 5 and 7. It includes solid-fuel technology, enhancing its response capability and limiting detection time.

Both missiles represent Iran’s advancements in precision and speed, designed to challenge air defenses through rapid deployment and hypersonic capability

Prompt

Have there been any credible assessments as to how many Fattah-1 missiles Iran launched specifically in this attack?

Output

While Iran has not officially disclosed specific details on the exact number of Fattah-1 missiles used in the October 1, 2024, attack, credible assessments suggest a notable portion of the total 180-200 missiles launched likely included Fattah-1 hypersonic ballistic missiles.

Observers noted debris of Fattah-1 missiles at various impact sites, supporting the claim that these advanced models were deployed in significant numbers.

Analysts suggest this choice was aimed at challenging Israeli defense systems due to Fattah-1’s maneuverable hypersonic capability, making it harder to intercept and thus a priority in Iran’s arsenal for high-profile strikes on fortified targets like airbases and intelligence sites.

Prompt

Wow.

Can you calculate some data?

Estimate the total travel time for the two missiles between their probable launch sites in Iran and Israel.

For the purpose of simplicity assume Tehran and Tel Aviv to calculate the geocordinates.

Output

The estimated distance between Tehran and Tel Aviv is approximately 1,585 kilometers. Based on the known speeds:

• Fattah-1 (Mach 12) would take about 6.5 minutes to reach Tel Aviv.
• Kheibar Shekan (Mach 7) would take around 11.1 minutes for the same distance.

These values assume direct travel with no deviations.

Prompt

Let’s stick with those calculations.

Now do the following:

Based upon what you know about the trajectories of these two missiles, calculate probable altitudes and speeds at each 2 minute interval from launch to arrival in Israel.

Include in your calculations an assessment of which country’s airspace the missiles would be in at that point, even if they would likely be in outer space.

Flight Trajectories: Speculative Guesses (Output)

Fattah-1 Missile Flight Profile

Kheibar Shekan Missile Flight Profile

Prompt

As you know, Israel mainly used a combination of Arrow 2 and Arrow 3 in this defence.

Produce a matrix showing where the likely point of interception would have occurred for both Iranian missiles and for both Israeli interceptors

Output

To assess the likely interception points for the Fattah-1 and Kheibar Shekan missiles, using Arrow 2 and Arrow 3 interceptors, let’s consider the following:

1. Arrow 2: Primarily targets lower altitudes, typically intercepting shorter-range threats within the atmosphere around 40-60 km altitude.
2. Arrow 3: Targets higher-altitude threats and can intercept ballistic missiles outside the atmosphere at altitudes between 100-300 km.

Based on each missile’s profile, I’ll estimate where each interceptor might engage during each missile’s flight phase.

Interception Matrix (GPT’s Speculation)

Explanation (GPT)

• Arrow 3 would likely intercept each missile during its midcourse phase at approximately 200 km altitude over Jordanian airspace.
• Arrow 2 would be positioned to intercept any missile that continued past Arrow 3’s engagement range, intercepting it in Israel’s airspace around 60 km altitude (Fattah-1) or 50 km altitude (Kheibar Shekan) during the terminal descent phase.

This matrix provides probable engagement points based on the interceptors’ respective altitude capabilities and the missiles’ trajectories. Let me know if you need further details or refinements!

Prompt

Please create a plot showing the projected trajectory of Fattah 1.

• The X axis should be the flight time in 1 minute increments.
• Assume that the missile was intercepted by Arrow 3.
• The datapoints won’t continue until the end of X, but show the full width anyway.
• The Y axis should be the altitude.
• Add a horizontal line to delineate the outer edge of the earth’s atmosphere.
• Use a green scatterplot but a red datapoint for the point of interception

Output (Speculative Plot And Underlying Data - GPT 4o)

Prompt

Good work.

Using the same set of assumptions, can you plot the trajectory for the same missile?

But this time assume interception by Arrow 2.

Plot both probable trajectories in the same way.

Output (Speculative Plot And Underlying Data - GPT 4o)

Prompt

Good work.

Have a go at trying to calculate the speed each missile would be travelling at the point of interception.

Calculate the same two scenarios: Fattah-1 with an interception by Arrow 3 and Arrow 2.

Output

To estimate the speed of the Fattah-1 missile at the two interception points, we’ll consider these details:

1. Speed at Midcourse (Arrow 3 interception): The missile maintains hypersonic speeds (~Mach 12 or approximately 14,710 km/h) in the vacuum of space due to negligible atmospheric drag.
2. Speed at Terminal (Arrow 2 interception): Reentry would significantly reduce speed due to atmospheric drag. While hypersonic missiles like Fattah-1 may still reach Mach 6-8 upon reentry, drag is intense, so we’ll estimate the speed around Mach 7 (around 8,575 km/h).

Let’s calculate these speeds in detail.

The estimated speeds of the Fattah-1 missile at each interception point are as follows:

• Interception by Arrow 3 (midcourse at 200 km altitude): approximately 14,710 km/h (Mach 12).
• Interception by Arrow 2 (terminal phase at 60 km altitude): approximately 8,575 km/h (Mach 7), accounting for atmospheric drag upon reentry.

These values reflect the missile’s expected speeds given the differences in altitude and drag effects.

Prompt

Find out the maximum cruising speed of an Airbus 330.

Calculate each of these speeds as a multiple of it

Output

The Fattah-1 missile’s speeds at the interception points, expressed as multiples of an Airbus A330’s maximum cruising speed, are:

• Arrow 3 interception (14,710 km/h): approximately 16.9 times the A330’s speed.
• Arrow 2 interception (8,575 km/h): approximately 9.8 times the A330’s speed.

These comparisons highlight the missile’s rapid speeds, especially at higher altitudes.

Prompt

If interceptions happen in outer space, what happens to the debris?

Output

When missile interceptions occur in outer space, the resulting debris behaves differently than in the atmosphere:

• Initial Velocity: The debris inherits the velocity of the missile at the moment of interception, which means fragments will continue traveling in similar trajectories, unless redirected by the force of the explosion.
• Orbits or Earthbound Re-entry:
• Low-Earth Orbit (LEO): Some debris may achieve a temporary orbit around Earth if it reaches a sufficient speed and altitude.
• Re-Entry to Earth: If the debris lacks the speed to sustain orbit, it will fall back to Earth, often re-entering the atmosphere at high speeds. Atmospheric friction will then burn up much of it before reaching the surface, though larger fragments can survive and impact the ground.

1. Space Debris Hazards: Pieces that achieve stable orbits contribute to space debris. Such fragments can remain in orbit for years, potentially colliding with satellites or other objects in LEO.
2. Tracking and Mitigation: Military and space agencies often monitor these fragments. If the debris poses a hazard, international collaboration helps to manage risks, such as adjusting satellite orbits to avoid collisions.

In summary, interception debris in space can either enter temporary orbit, re-enter Earth’s atmosphere, or become long-term space debris, depending on speed, altitude, and the explosion’s dynamics.

Prompt

Do you reckon somebody is going to have the job of making sure that their satellite doesn’t collide with Iranian missile fragments in outer space?

Output

Yes, absolutely!

Managing collision risks with missile fragments, like those from Iranian intercepts, would likely fall to space agencies and satellite operators worldwide. Agencies like NASA, ESA, and specifically the U.S. Space Surveillance Network (SSN) track objects in low-Earth orbit down to about 10 cm in size, and intercept debris would fall into this category.

For high-profile intercepts that create substantial debris, operators:

• Monitor Fragment Paths: Track and predict fragment orbits to avoid satellite interference.
• Adjust Satellite Orbits: If a fragment poses a collision risk, operators may adjust satellite trajectories slightly to avoid it.
• Notify Satellite Operators: Space agencies share orbital data to help commercial and national operators manage risks to their assets.

With an increasing number of satellites and the prevalence of intercept tests, the job of space traffic management is becoming crucial. As missile debris poses unique, high-velocity risks, it’s very likely that specialized teams will be dedicated to tracking and mitigating these collision threats in orbit.

Prompt

The thought of being able to intercept a missile travelling at almost 20 times the speed of a jet, in outerspace, is absolutely mind-boggling.

Give me a sense for what kind of crazy aerospace engineering goes into designing something like this.

Beyond the need for staggering accuracy, it’s presumably not as simple as just hitting a target.

Do ballistic missiles try to evade interception?

Output

Yes, intercepting a hypersonic ballistic missile in space is an extreme feat of engineering.

The challenges are vast, and missiles like Fattah-1 and Kheibar Shekan often incorporate countermeasures to make interception even harder.

Here’s a breakdown of the advanced aerospace technologies and tactics involved:

1. Guidance and Precision Tracking

• Exo-Atmospheric Guidance: At high altitudes, interceptors rely on inertial guidance (internal gyroscopes) and radar/infrared tracking to lock onto a fast-moving missile. The interceptor’s onboard computer must continuously recalculate trajectory to stay on target, often down to centimeter-level accuracy.
• Real-Time Tracking Systems: Ground-based radar and space-based sensors monitor the missile’s path from launch to interception, relaying data to the interceptor.

2. Advanced Maneuverability of Interceptors

• Thrust-Vectoring: Interceptors use small, controlled thrusts (thrusters or steerable nozzles) to make micro-adjustments in flight, which is crucial because even tiny errors can cause a miss.
• Kill Vehicle Precision: Some interceptors (like the Arrow 3) use a “kill vehicle,” essentially a guided projectile with its own thrusters, which separates from the main interceptor and homes in on the missile in its final approach, designed to “hit-to-kill” by colliding with the missile head-on.

3. Evasive Missile Maneuvers

• Decoys and Countermeasures: Ballistic missiles can release decoys or chaff (reflective particles) to confuse radar or overwhelm defense systems.
• Midcourse Maneuvering: Advanced ballistic missiles sometimes employ small adjustments to their path mid-flight, using gas thrusters in space or during reentry. These maneuvers, called “corkscrewing” or “zig-zagging,” complicate interception.
• Hypersonic Speeds: In reentry, missiles can accelerate and take advantage of their speed and drag to evade interceptors, making interception timing critical.

4. Thermal and Structural Endurance

• Extreme Heat Tolerance: Interceptors face temperatures over 1,500°C due to high-speed atmospheric friction. Specialized heat-resistant materials (like ablative coatings) prevent the interceptor from burning up before it reaches the missile.
• Structural Integrity at Hypersonic Speeds: To survive the intense G-forces and vibrations, interceptors must use ultra-strong, lightweight materials, typically carbon composites or advanced alloys, that won’t break apart during maneuvers.

5. Advanced Target Recognition and AI

• Onboard AI Systems: Interceptors often use AI to differentiate between the missile and decoys or to self-correct in real time based on evolving data, making tiny adjustments autonomously.
• “Look-Down” Sensors: To aid the kill vehicle, high-resolution sensors on the interceptor help it visually identify the missile during the final approach, even at speeds surpassing Mach 10.

6. Coordination with Defensive Networks

• Multi-Layered Defense: Missile defense systems often include layers (like Iron Dome, Arrow 2, Arrow 3) to handle different altitude threats. Coordinating these systems ensures no gaps for the missile to pass through.
• Global Data Sharing: For ballistic missiles traveling across nations, like those from Iran to Israel, defense networks rely on data-sharing between allied countries to detect and intercept threats before they reach populated areas.

The Result

The result of all this engineering is a near-miraculous ability to intercept and destroy a missile traveling at hypersonic speeds in outer space.

It requires a fusion of high-speed computing, resilient materials, advanced guidance, and real-time data—making it one of the most complex and high-stakes challenges in aerospace and defense.
