I would start by saying that each year the materiel group moves over $5 billion in programs on an annual basis. That's not only new equipment coming into service, but providing the in-service support to existing fleets. Over the last few years, four C-17s have been delivered on time and on budget and 17 C-130Js, the Hercules aircraft on time and on budget. When I talk about being on time and on budget, I'm talking about the latest TB approval for schedule. Sometimes those schedules were updated, but based on the approvals received for definition and implementation, those projects were delivered on time and on budget.
To meet an urgent operational need in theatre, Chinook-D medium-lift helicopters were provided to the forces in Afghanistan, as were Leopard tanks. I was actually at the Treasury Board Secretariat when the secretariat worked through the weekend to deliver the Leopard 2 tanks that were urgently needed in Afghanistan, to make sure we got them to the troops in theatre.
At the moment, as I speak, we're still working on the Halifax class modernization. It's a $4.3-billion project and a major success story on both coasts of the country. All 12 frigates are being modernized. The most recently modernized frigate is now participating in operations in support of the Operation Reassurance mission with the allied effort in Ukraine.
We've taken advantage of opportunities to buy a fifth C-17 on extremely short notice. We were advised that Boeing was shutting down the production line and had 10 aircraft left and, from flash to bang, that was about a six-month process to get that fifth aircraft, which will be delivered any day now.
We were also told that the production line for the wing kits for the Aurora aircraft, which are being flown to great effect in theatre in support of the mission in Afghanistan, was going out of business as well. We managed to get four wing kits at the very last minute in very fast time to make sure of that, and rather than having just 10 Aurora aircraft available for operations, we increased the number to 14. Again, that was done very quickly.
