ST. LOUIS, MO (KTVI-FOX2now.com) - There's concern about Boeing's C-17 aircraft. President Obama's budget proposal calls for cutting several weapons programs, including the C-17. Eliminating the C-17 program could mean eliminating jobs in the Gateway City.

When unveiling his budget, President Obama said, "We save money by eliminating unnecessary defense programs that do nothing to keep us safe. One example is the 2.5 billion dollars that were spending to build C-17 transport aircraft."

C-17s have been used extensively in flying supplies and troops to earthquake ravaged Haiti. Senator Kit Bond says they're desperately needed.

Four years ago, the Defense Department decided to stop production of the C-17 because it had acquired the 180 it requested.

"Yet every year since, congress has provided unrequested money for more C-17s the Pentagon doesn't want or need. It's waste pure and simple," says the President.

The C-17 is one of Boeing's premiere aircraft. It supports a thousand jobs in St. Louis, jobs that could be cut, if the program is cancelled.

Senator Kit Bond said," The president's mixed up spending priorities also threatens workers right here in St. Louis and our nation's air lift capacity."

You may recall, the government tried to eliminate the C-17 program in 2009, but lawmakers saved it. Bond says he'll fight for it again this year especially since the Pentagon now has the ability to retire C-5As.

Sen. Bond says," They need the C-17s to replace those aircraft. I'm going to make that point very loudly in the appropriations process. We'll see whether we're successful."

U.S. Senator Claire McCaskill says she will also fight to save the C-17 program. She released the following statement:

We have known for years now that the c-17 has been flying into a strong headwind. Over the last three years, secretaries of defense and presidents from both political parties have uniformly sought to end its production. Since coming to the senate, i have fought side by side with my colleagues against these recommendations and we have successfully prevented an end of production. At a time when the c-17s first-rate capabilities are in increasing demand around the world, i will once again fight for this plane. I will be looking particularly closely at the substantial readiness problems with the c-5, the only other strategic airlifter. It seems long overdue that we should retire the oldest c-5 planes that arent working and replace them with the c-17, a plane that we know works and is produced at a fair cost.

Boeing released the following statement reacting to the proposed defense budget cuts:

"What we have been able to see so far of the proposed DOD budget and the QDR raise key public policy issues that will be discussed in the days, weeks, and months ahead.Critically important among these issues are the future of America's defense industrial base and maintaining healthy competition in the defense industry. As a matter of public policy and defense doctrine, America has invested in developing and maintaining a national defense industrial base that meets the evolving needs of the military while providing the best value for the taxpayer. It is a true national asset - built over many years by investing in highly-skilled engineering and a high-tech manufacturing workforce and by developing best-of-industry practices. The Congress now begins its work towards passing the overall budget and the DOD segment. We will continue to study the budget proposals being made for potential impact to Boeing, the industry, its industrial base, and to its workers, as well as important policy debates in other critical areas such as healthcare, energy, the environment and education. Meanwhile, the men and women of The Boeing Company will continue to perform at the highest possible level to deliver the best value to our customers and to the taxpayer."
