                                                                   Exhibit 99.1.


           U. S. STEEL GROUP SEES RESULTS IMPROVED OVER FIRST QUARTER

          PITTSBURGH, July 13 - Responding to recent inquiries, USX
Corporation's U. S. Steel Group (NYSE: X) said second quarter earnings before
interest, income tax, depreciation and amortization (EBITDA) are expected to be
approximately $50 million to $60 million, based on revenues of approximately
$1.7 billion.  This compares with a negative EBITDA of ($28) million on revenues
of $1.5 billion in the first quarter of 2001.  The foregoing includes net
pension credits of approximately $35 million in the second quarter and $41
million in the first quarter.
          Commenting on the current range of analysts' expectations as reported
by First Call (a loss of $1.06 to a loss of $0.50 per share with an average loss
of $0.72), the company said it expects to be nearer the $0.50 loss.
          The company's domestic steel shipments in the second quarter were 2.6
million tons, a 10 percent improvement over first quarter levels.  Shipments
from U. S. Steel Kosice were 1.1 million tons, over 40 percent higher than the
first quarter.
          USX Corporation's U. S. Steel Group quarterly financial results are
expected to be announced on Monday, July 23, 2001.
