Delta IV vs. Atlas V

Here is a compilation of planned (as of July 31, 2003) Delta IV and
Atlas V launches for the next few years. This list assumes that
three GOES launches will be transferred from Delta III to Delta IV.

Delta IVM(+) Delta IVH Atlas V-4XX Atlas V-5XX
2003* 1 - 1 1
2003 1 - - -
2004 2** 1 1** -
2005 2 2 1** 1
2006 1 - 1 3**
2007 1** - 4 1
2008 2** - 1 1
2009 1 - 2 0
2010 2 - - -

TOTAL 13 3 11 7

* Completed to date
** Includes one NASA or commercial launch - all others launches
are EELV missions for U.S. Air Force.

Observations:

1. 2004 looks like a slow year for Atlas V, but Delta IV
operations become comatose after 2005.

2. There are no Heavy missions planned after 2005.

3. Current plans show an average of only about 4 launches per year
for Delta IV and Atlas V combined.

4. Both of these rockets cannot survive under existing market
conditions.

I think I may be in a position to influence that...

Both will almost certainly survive to provide redundant access for
military payloads. Commercial viability was/is essentially moot - they
are required national resources. All that a viable commercial market
does is reduce the price.

There's been talk about how 'required' that required access is.

It puts Boeing in an interesting position though. Suppose they say
"We're not interested in doing Delta IV anymore, it doesn't pay." to the
US Gov. is the government going to have to come back with Big Money(TM)
to tempt them?

There is no, none, zero, nada, debate about required military access
to space. In fact, we can't build the payloads nearly fast enough to
supply the rapidly expanding need.

Whether dual-string capability is required, or merely highly
desirable, could potentially be debated, but I bet they won't make that
mistake again.

The fact that the "ban" on bidding was not total suggests that the
punishment is intended as a motivation to Boeing to correct their ways.
It could easily have been a death blow. And if the squealing gets loud
enough, I would anticipate the "ban" being modified.

Another complicating factor is the Russian-supplied parts on the
Atlas. That significantly improves the situation for the Delta.

I don't see how it's in anyone's interest to kill off the Delta IV
completely. I bet even Vance Coffman would agree if you asked him off
the record.

In time-honored tradition. But I doubt that we are talking "big"
money in terms of government contracts. Big compared to "cheap access to
space" delusions, but that's largely a figment of people's imaginations
anyway.


Just my opinion, of course. But I wager that Boeing and Lockheed
will still be in the launch business in 10 years.

We don't have true dual-string capability... both vehicles are
dependent on the RL-10 engine. There's been some work on a different
upper stage engine to provide true dual-string, but in today's
unprofitable market, I wouldn't bet on it ever getting off the ground.

The RL60 will begin testing this summer. Don't know the status of
the MB-60/MB-35.

Luckily, the RL-10 is a fairly mature engine design. If there are
problems, you'd think it would be due to recent design, manufacturing,
or operational changes.

I am surprised the Atlas V was allowed to compete for government launches
because of this.
Russians get mad and boom we lose a good portion of our launch capability.

Depends.
Is China making threating noises towards Tiawan, are the Russians backing
them?
Or something else along those lines.

I think LockMart has a Plan B in case those engines suddenly become
unavailable, though it may take time to implement. That batch of
NK-33s that Aerojet now owns, lock, stock and barrel, might actually
fly after all. Ironic, isn't it?

I think that they were making exactly that threat to avoid getting
slapped over the corporate espionage, but the Air Force called their
bluff.
