The Enduring, if Unsettling, Allure of Defence Stocks

Every so often, a business deal comes along that’s more than just numbers on a page. It’s a story. And the recent tale of Colombia buying Swedish fighter jets is, to me, a particularly telling one. Saab, a name many associate with defunct cars, just landed a €3.1 billion contract. This isn't just a win for the Swedes. It’s a flare in the sky for investors, signalling a fundamental shift in a sector that, for better or worse, never really goes out of fashion.

A Changing of the Guard?

For decades, if you were a nation outside the big geopolitical clubs and needed new military kit, your first port of call was likely America. It was the default option. Colombia’s decision to equip its air force with Swedish Gripen jets, however, shows the game is changing. They looked at the established menu and decided to order off-piste.

This isn't about politics so much as pragmatism. It tells us the marketplace for high-end weaponry is becoming more, well, normal. More competitive. Nations are shopping around, looking for the best technology and the best long-term value, not just the most familiar flag. For an investor, a competitive market is an interesting market. It creates opportunities for companies that were once considered second-tier players to suddenly find themselves with a very full order book.

The Great Global Upgrade

What’s driving this shopping spree? It’s not necessarily a sudden global panic. It’s something far more mundane and, from an investment perspective, far more reliable. It’s obsolescence. All over the world, military hardware from the 1980s is creaking at the seams. Like a classic car that’s now more trouble than it’s worth, maintaining these old systems is becoming prohibitively expensive. A full-scale upgrade isn't a choice, it's an inevitability.

This creates a predictable, multi-decade cycle of demand. When a country buys a fleet of jets from a company like Boeing, they aren’t just buying a product. They are buying a 30-year relationship filled with maintenance contracts, software updates, and spare parts. It’s the ultimate subscription model, and it provides a bedrock of revenue that is wonderfully insulated from the whims of consumer spending.

More Than Just Metal Birds

It’s also crucial to remember that a fighter jet is not a single product. It’s a flying collection of incredibly complex systems built by a whole host of specialist companies. The airframe might have one name on it, but the radar systems could come from Northrop Grumman, and the advanced electronics from a firm like Leonardo DRS. It’s a complex web, and understanding how these pieces fit together is key. You can see a broader breakdown in this piece on Defense Stocks Explained | Global Military Upgrades, but the gist is simple. Once a country buys the plane, they’ve bought into the whole ecosystem for the next thirty years.

This ‘lock-in’ effect is a powerful economic moat. Switching suppliers isn’t like changing your brand of coffee. It involves retraining an entire generation of pilots and engineers and building entirely new infrastructure. In short, it rarely happens.

A Pragmatic Investor's View

Of course, investing in defence is not without its complications. The sector is beholden to the shifting winds of politics, and contracts can be delayed or cancelled by a change in government. There are also, quite rightly, ethical considerations that will rule it out for many.

However, for those taking a purely financial view, the logic is hard to ignore. We are looking at a sustained, global modernisation trend fuelled by necessity, not aggression. The long contract cycles and high barriers to entry could offer a degree of stability that is hard to find elsewhere. It’s not exciting in the way a tech start-up is, but perhaps that’s the point. It’s about long-term, predictable demand from the most reliable customer of all, the state.

Deep Dive

Market & Opportunity

• Saab secured a €3.1 billion contract to supply Colombia with Gripen fighter jets.
• Military equipment operates on 20 to 30 year replacement cycles, creating sustained demand.
• Defence contracts often include comprehensive training programmes, maintenance support, and technology transfer, ensuring revenue streams for decades.

Key Companies

• The Boeing Company (BA): Manufactures commercial aircraft and military systems, including the F/A-18 Super Hornet and various missile defence platforms, benefiting from long-term government contracts.
• Northrop Grumman Corporation (NOC): Manufactures advanced radar systems, electronic warfare equipment, and autonomous systems. Key programmes include the B-21 Raider bomber and space and missile defence systems.
• Leonardo DRS, Inc. (DRS): Provides advanced electronics and computing systems for military platforms, including thermal imaging systems, power management solutions, and network computing technologies.

Primary Risk Factors

• Political changes can affect defence spending priorities.
• International arms sales are subject to regulatory scrutiny that can delay or cancel contracts.
• The sector faces ethical and ESG considerations as it profits from military conflicts.
• Long development cycles and significant upfront research investment can lead to earnings volatility.

Growth Catalysts

• A global wave of military modernisation is driving nations to upgrade aging, Cold War-era equipment.
• The "platform effect" locks customers into a supplier's ecosystem for decades of parts, maintenance, and upgrades.
• Nations are diversifying their defence partnerships, creating opportunities for a wider range of international contractors.
• Technological evolution in AI, hypersonic weapons, and space-based defence is creating entirely new market segments.
