Aug 4 (Reuters) - Firefly is targeting a valuation of up

to $6.04 billion in its U.S. listing, the company said in a

filing on Monday, raising its pricing range amid heightened

interest in space companies.

The company is seeking to raise up to $696.6 million by

offering 16.2 million shares priced between $41 and $43 each.

It had last week launched its IPO roadshow and was

initially aiming to raise as much as $631.8 million at a $5.5

billion valuation at the top of its range.
