Cash-starved Boeing, contending with massive financial losses from a crippling strike and years of operational and safety problems, is turning to major banks and Wall Street to raise tens of billions of dollars in cash.

In a regulatory filing early Tuesday, the company announced plans to borrow $10 billion from a consortium of banks. It also separately announced plans to raise $25 billion by selling stock and debt.

The company’s debt surged in the last six years as Boeing reported core operating losses of more than $33 billion. Its commercial airplane production has ground to a near halt by a month-long strike by 33,000 members of the International Association of Machinists.
