. >> let's talk about another force, your latest briefing for csic is about the cost of the space force. what are the estimates on the space force? >> i went and looked at a bottom up estimate if you create a space force, what's it going to involve. the vast majority of the funding for a space force would be transferred out of accounts that are already existing today in the services budgets. most would come from the air force, since the air force does most of the space activities today, about 85% of the funding year to year, and so you would move all of that into a new budget, so that's neutral. it doesn't add overall to the budget. then you do have to add a new headquarters, staff on top of that for a new service, and create a new secretariat staff for a secretary of the space force. my system were depending on how large you scope this space force, the additional cost is going to be from $300 million to about $550 million per year. interestingly that's less than the cost of the audit. >> if you want to read more, how much will the space cost is the csis briefing, at csis.org. todd harr
