There has been a lot of progress made since the “Strong, Secure, Engaged” defence policy was released in 2017. Since 2019, in some cases, projects have had some delays. However, we've also advanced some projects ahead of their originally intended timelines, such as the armoured combat support vehicle project, which is currently seeing delivery of vehicles well ahead of the initial timelines. We've also advanced the replacement of two of the older Challenger business aircraft that are part of the RCAF's fleet.
We have moved many projects through various phases and gates of the project approval processes. As I mentioned earlier in my opening remarks, we have 74 equipment projects currently under the materiel group's leadership in the phases that we are working on alongside our PSPC colleagues. These are projects for which we are developing the requests for proposals as part of the procurement process, or that have moved through to implementation. We're seeing delivery of equipment now.
We are seeing good progress. There are challenges. It's complex work, which COVID-19 has confounded over the past number of years, but we are looking forward to further progress.
