British defence strategy falters as tank numbers fall short
The modernisation of British Challenger 3 tanks reveals significant deficiencies in the United Kingdom's defence strategy, according to Andrew Latham, a professor of international relations at Macalester College in St. Paul. He estimates that the British might have fewer tanks than Poland.
The British defence strategy, which relies on the modernisation of Challenger 3 tanks, has faced criticism due to the limited number of units. Expert Andrew Latham from Macalester College points out that the planned 148 Challenger 3 tanks are too few in the face of increasing threats in Europe.
Challenges of the British defence strategy
- The lesson from Ukraine is brutal but clear: tanks still matter, and you need a lot of them. They get destroyed. They need to be replaced - Latham asserts. The expert emphasises that in light of the ongoing conflict in Ukraine, the United Kingdom must focus on rebuilding its armoured forces. Otherwise, "Challenger 3 will remain merely symbolic."
Latham explains that the problem with the Challenger 3s is that there are too few of them. The British plan to upgrade only 148 Challenger 2 tanks to the new Challenger 3 standard (with a total of 157 older units remaining in the British army). He adds that the United Kingdom does not need thousands of tanks but must have enough to withstand attrition, support allies, and deter opponents.
- 148 tanks simply do not constitute mass. They represent a boutique capability masquerading as a deterrent. In truth, Britain’s armoured force is now little more than a symbolic gesture - Latham adds.
Shortages and delays
Despite being ambitious, the Challenger 3 programme faces delays and shortages. Latham notes that the current number of tanks is insufficient, and the British armoured forces are merely a symbolic gesture. Compared to other NATO countries, the United Kingdom has fewer tanks than Poland or Germany (Poland's arsenal comprises approximately 1,000 main battle tanks).
- Fewer than even Italy, whose land power posture has long been an afterthought. And while the British Army likes to cite "capability over quantity," that mantra rings increasingly hollow in an era of industrial war. No serious defence planner would argue that Britain should match Russia tank-for-tank. But they might reasonably ask why one of NATO’s major powers fields an armoured force smaller than many second-tier allies. This is not just a procurement issue – it’s a credibility issue - Latham points out.
Challenger 3 tanks
To clarify, the Challenger 3 is actually an advanced modernisation of the Challenger 2 tanks, which are still in use. In this version, the chassis from the Challenger 2 has been retained but redesigned and additionally armoured. The tank is equipped with new modular armour and an active protection system, significantly enhancing crew safety. For the Challenger 3, the British decided to forgo domestic weaponry in favour of a solution used in most Western tanks. They chose the Rheinmetall 120 mm L55A1 gun, which aligns with modern ammunition standards used by NATO countries.
