Space Defence – The Game of Three Levels of Attack

 

The Domain of Space as we Know Today

For any well-read and reasonably aware individual, it is well known that many countries have satellites and missiles, fewer have missile defence and space programs and extremely few have sent humans to space or have anti-satellite weapons. In this article, we'll concentrate on anti-satellite warfare before placing it the diplomatic context.

There are three parts to taking out any satellite in orbit - (1) Identification of target (2) Monitoring and forecasting trajectory (3) Attack

Anti-Satellite (ASAT) Warfare 

You need to have eyes at space to identify and track down the target satellite. These are typically electro-optical telescopes, ground based radars, space based telescopes and radio frequencies. Technical capability is a major constraint here as the space assets / satellites can be positioned at any altitude between LEO and GSO/GEO with varying velocities and different inclinations, eccentricity and synchronicity of orbits. Vast space requires higher resolution images that are best supported by X band radars. X band radars are the most contentious part of the THAAD battery and the S 300 missile defence as they enable deep surveillance capabilities.

The ARES Orbital Debris Program Office of NASA JSC monitors all space debris. US is able to perform risk assessment with help of Standards, Practices, Procedures and Software. It also conducts Hyper Velocity Impact Technology experiments at their Houston facility with a lot of other scientific research through their civilian arm of the space program. The United States SSN, a part of USSTRATCOM, monitors all space objects (~8000 of which ~560 are satellites) larger than 10 cm/10 pounds orbiting the earth. The same objective of monitoring is also a part of the mandate for NORAD-USNORTHCOM. As you can see, a unified combatant command with additional military hardware like AWACS are deployed by for the stated purpose of monitoring illegal air movement of drugs and homeland defence.

Once the target's orbital path is forecasted, the decision to attack the target is made using one of the five possible techniques. Three of the techniques involve kinetic kill warheads and two use electromagnetic beams. Let us consider them one by one.

ASAT Techniques

The first method and the earliest method is ground / sea based ballistic missiles as kinetic kill warheads. China successfully tested this method on a LEO satellite from a mobile Transporter-Erector-Launcher (TEL) in 2007. This is similar to the Exoatmospheric Kill Vehicle concept of the US where the boost missile launches the kill vehicle in an intercept trajectory at speeds of about 10 km/s. This is a high velocity head-on collision with the target satellite. The US has successfully used RM161 SM3 in 2008 and Russia has successfully tested PL19 Nudol in 2016 for the same purpose. In terms of classification though, these are anti-ballistic missiles that were used.

The second method is the use of fighter or cargo aircraft to launch similar kinetic kill vehicles. The ALBM technique was tested during late 50s and early 60s by the US with limited success. The PGM-17 Thor program of launching IRBM from cargo aircrafts as a stop gap measure by USAF were more successful but had competitive rivalry with Jupiter missiles developed by US Navy. The intention was also to carry thermonuclear warheads as a second strike capability from UK. The US Vought ASM135 launch from a modified F15 was successful in 1985 but the program was later abandoned.

The third technique is the use of a space based asset to launch a kinetic kill warhead. The idea originated in the 1960s with IS fighter satellite program started by the USSR as a co-orbital weapon that would approach close enough to the target and explode shrapnels to destroy it. The 14F11 Naryad system is believed to be space based battle stations being pursued by Russia. The US has also pursued similar projects like XSS-11, NFIRE and Space Based Interceptor for space launched ASAT warheads.

The fourth technique is the use of lasers, either launched from ground or orbital space stations. The Soviets brought together all research under one umbrella in their 12th five-year plan that ended up in launching the unsuccessful SkifDM/Polyus station. The Soviets were responding to the four stage US ASAT initiative starting with deploying over 4500 kinetic interceptor satellites better known "Brilliant Pebbles" in LEO.

The fifth technique is the use of satellite jamming typically from ground based devices with electromagnetic waves. While this is not as destructive as kill vehicle, it still requires the three steps of identification, forecasting trajectory and jamming a particular group of channels / introducing malware from an exposed port. The speciality of this technique is that it can be deployed terrestrially near receiving stations at marginal cost.

Our Option(s)

We need to relate the economic and cultural context while looking at our options. Many developing nations forego their cultural identity and traditional wisdom in the great race to achieve economic parity. It is not that the western powers have better stories or morals, they use technology to capture and fashion the imagination of any bright young mind. These stories wire coming generation into the societal beliefs, ethics and norms of the west, emboldening their economic prowess. In economics, the primary driver of GDP growth is technology and this is a gap that is increasingly widening in favour of the west. Choosing between ASAT and not is like choosing between the gun and sword. The sane smaller guy would always go in for the gun. 

My article is neither a deep dive into the cost benefit analysis of any of these techniques nor an opinion on the superiority of one over the other and also not a critique of ASAT programs. The only question worth asking is, when do we decide to have our own ASAT? We may not be attacking but we sure need to be defending across all of them. Any such layer of defence needs to have an ecosystem that makes it self-sustaining. The domain of space science and technology is immense and we need to invest wisely. While the core R&D is confidential, a partnership with our academic institutions and industry players may play a pivotal role in accelerating our growth journey. 

Is it pre-emptive attack the only viable defence option available in Space? The rest of this article attempts to answer this very question. 


Our Typical Imagination of Space

“To boldly go where no man has gone before” is perhaps the most well-known dialogue from “Star Trek”. Space makes us want to explore the unknown frontiers, discover mysteries, explain phenomenon and to many take photos, talk to far off friends and send videos. The utilization of space with assets has been mostly to the same effect as the imagination I mentioned. All this silently presumes that humanity is united and is run like an efficient one-party communist style leadership. And that there are the heroes in men that lead this space race. This dream is not a vision, but more wishful thinking.

CubeSats take away the immense cost and technological might required for space presence and show how space is being democratized. Space where growth is happening for each and it would happen most probably in the manner we have grown most, i.e. by competition. But let’s come back to this towards the end. This article’s focus is to lay the philosophical foundation of the new realm of defence in space.

The Imperative of Security in Any Idea of a Nation

We humans are still a species that is still tribal in mindset. Our rapidly increasing population has further entrenched this feature, in spite of ever strengthening opposing force of technology. Animals have territories, and educated Homo Sapiens have borders. Yet we progressed exponentially. It happened not because borders were removed but because they were negotiated.

A collection of humans called a nation tries to preserve and perpetuate its way of living. Since it is the judged making the judgement, we ourselves won’t ever agree on which nation deserve to take over the world on its merit and the rest should cease to exist. We’ll play the game of international trade and politics. What keeps us busy growing and negotiating is our confidence in our security, military if I had to state it narrowly. Now we are crossing the decades of “soft powers” where the word military is replaced by culture, though again it defines security narrowly.

The narrow definition of security is the reason why it ends up being reactive and never enough. The alternative is strength, which is best defined as heightened state of alertness + scalpel precision moves at favourable inflexion points. Let’s go through how the world looks from the lens of alertness, which for a species that still fighting for survival, I would call “level of attack”.

A vicious cycle exists in the current geopolitical landscape where more power means more money and more money means more power. But there is another corollary to this that I’ll come to towards the end.

The Low Level of Attack – Hibernate Mode

In this mode we choose to actively grow when the environment is suitable and we choose to hold on to the status quo till the bad environment blows over. The massively complex space programme grows in good times through authentic intentions of a few despite the bureaucracy. We seek to grow for our own needs and aspirations with our limited means and are not willing to know too much about our neighbours, let alone the other side of the globe. Our rockets can launch our satellites so that we can watch our crops grow well and provide better forecast before disasters. In the worst case of a battle, our armed forces and planes may use our own navigation system but that’s all there is to it. We close our eyes to what is visible but is not our concern. This mode is better known as “Strategic Restraint”. In the animal world, it is better known as hibernation of the reptiles. The reptiles did rule the earth, but those dinosaurs one day went extinct.

High Level of Attack – Dominate Mode

This is the mode of existence where the nation chooses to push its way by requests, coaxing, hard bargaining, sabre rattling and all-out war. In geopolitics this translates to trade treaties, economic unions, sanctions, war games, human rights and militancy elimination. In space, it means active use of spy satellites, blocking satellite communication, listening to all communication routed through hardware and if required, spreading misinformation and computer viruses. Anti-Satellite (ASAT) weapons have been successfully operationalized by US, Russia and China. While the discussions continue over the choice of method (laser/missile ground/air launched), the feasibility of hitting targets at variable altitudes given redundancy and space debris causing collateral damage, ASATs continue to be developed as a retaliatory if not offensive tactic.

Note that there is unrestricted use of all traditional means of warfare with impact multiplicatively increased by using space tech as the fulcrum. Space is utilized seamlessly with military, IT, diplomacy and trade & finance as it is with movies, telephones, education, medicine and video conferencing. Each opportunity that becomes available for increasing the nation’s might is exploited. Superpowers would typically be in this mode to sustain their hegemony, even though it is taxing on resources that can be more optimally utilized in the long run. US' proposed space force as a separate wing in the armed forces is the first move in of a superpower in this mode.

The Middle Level of Attack – Peace Mode

The middle path is usually the most balanced mode of living. Unlike the hibernation mode, we choose to see, hear and sense everything for everyone. And unlike the dominate mode, we act only in those cases with a minimum force when events and things would provide exponential extremely long run favourable returns. This means we understand and create all the cutting edge in science and technology, weaponize most of it, and yield hardly a few. It is important to note that in the Peace Mode we deploy means to protect our space assets. We are doing what our species did to become the masters of the earth – we stayed alert for the lion through generations, till finally we created our own jungle and forced the king lion to stay within the “national park” as we saw fit.

Foundation for Future Dominance in a No Man’s Land

Science fiction and artists’ imaginations have spoken a lot about what our future space world would be like. More often than not, they were reflections of freedom from their respective state of world. Perhaps a more actionable imagination would come if we can imagine a current nation with its citizens inhabiting different planets. The time gap between two parts of any nation and the globe would be large enough to make the theory of demand and supply in economics to fail. More simply said, goods produced on one planet would be sold after 20 years on another planet – so what drives a nation’s monetary / fiscal policy or target inflation/interest rate or its exchange rate and trade pacts?

The technology trend driving this growth is creating an engine to create and consume more data, way beyond what humans’ minds can manage. The only way left is to allow machines to manage growing needs of machines i.e. machines start taking over decision making over large data sets using Artificial Intelligence (AI). No prizes for inferring that automation via AI is a prerequisite for survival in space.

We had left two dangling points regarding competition and vicious circle of money and power in the beginning. Our biggest strength arguably lies in large scale cooperation across vast numbers of people. Competition between groups needs cooperation within the group. Competition exists to have more power and money. Money and power tend to concentrate not within people but organizations and institutions. Putting these together, we are looking at a space era where a nation would be philosophically defined as the group of homo sapiens living across planets that choose to create organizations and institutions best preserving and perpetuating their way of life. The components of that imagination are covered in a later article.

In conclusion, the peace mode of space age reverberates with thoughts of two of the greatest founding fathers of our nation. Gandhi once said quoting Shri Rabindra Nath Tagore, "I hope I am as great a believer in free air as the great Poet. I do not want my house to be walled in on all sides and my windows to be stuffed. I want the cultures of all the lands to be blown about my house as freely as possible. But I refuse to be blown off my feet by any". We need our vision of our sanatan civilization to preserve our way of life and at a tactical level this means we have our ASAT now.
