- I would like to see a source for this. The Soviets tended to prefer automated

- shouldn't be too much trouble qualifying crews.

- In ten years of operation Shuttle has not come down in price very much.
- As to additional flights reducing cost, it won't happen since Shuttle if
- flying at maximum rate now and CAN'T fly any more.

-
- A government report (I think it was 'Launch Options for the Future') said
- that there is plenty of facilities available to greatly increase the
- rate of Atlas launches. HL Delta goes up from an unused launch complex and
- all the costs you mention are included.

-
- The relevant government reports says larger launch rates can be sustained.
- This will provide better utilization of ground facilities which will reduce
- costs even more.

-
- 1. It is a commercial procurement. The government isn't buying a launcher
- but launch services. If the contractor doesn't deliver the payload, he
- doesn't get paid. The govenrment will not be paying for the development
- of HL Delta nor will it own the design. The contractor has every incentive
- to keep costs in line since he looses $$ otherwise.
-
- 2. The vehicles in question use mostly off-the-shelf parts with wide safety
- margins. This works to reduce costs and increase reliability.

-
- Because the rules are different. Before with cost plus contracts it was
- to a companys advantage to add costs. With this effort where only services
- are being purchased, that won't work.

-
- EXACTLY. Since we are making the government a real customer it will
- work just like Boeing. Now the govenrment is simply another buyer of
- launch services just like Intelsat (which McDonnell Douglas and GD
- already serve).
-
- Don't get hung up on HL Delta or Atlas. We aren't paying to develop
- them. All we are doing is buying launch services from the lowest bidder
- and it may not be either of those vehicles who get the contract.
