BAGHDAD, Iraq (CNN) -- U.S. forces plan to drop more than 1,500 bombs and missiles across Iraq in the first 24 hours of its "shock and awe" campaign that began Friday, Pentagon officials said.

Defense Secretary Donald Rumsfeld said the air campaign had shaken up the regime of Iraqi President Saddam Hussein, which he said is "starting to lose control of their country."

"The confusion of Iraqi officials is growing," Rumsfeld said at a Pentagon briefing. "Their ability to see what is happening on the battlefield, to communicate with their forces and to control their country is slipping away."

Rumsfeld said the bombing was stepped up Friday after senior Iraqi officers failed to turn against Saddam following initial U.S. airstrikes Thursday, including one aimed at Saddam himself, and a U.S. and British invasion of southern Iraq.

"What we've done so far has not been sufficiently persuasive," Rumsfeld said.

Rumsfeld said he did not know the fate of Saddam or whether leadership had changed hands, saying he only had "scraps of information."

A top Iraqi military commander surrendered to U.S. Marines Friday, along with his top deputy, American military officials told the New York Times.

The commander was in charge of Iraq's 51st Division, a regular army unit deployed in southern Iraq directly in the path of the allied invasion.

In the first strike against Iraq Wednesday night, coalition forces targeted a residential compound in Baghdad where Saddam, his sons and other top officials may have been hiding, according to U.S. officials. An intelligence service headquarters and Republican Guard facility in the city were also hit.

"There's no question but that strike on that leadership headquarters was successful," Rumsfeld said. "We have photographs of what took place. The question is, What was in there."

In an attempt to convince the world that Saddam survived the bombing, Iraqi state television broadcast pictures of what it said was the Iraqi leader meeting Friday with his son Qusay.

White House press secretary Ari Fleischer said, however, the U.S. has "no concrete facts" to indicate Saddam or his sons survived the airstrikes.

Punishing air attacks
The punishing air attacks rocked the Baghdad night Friday, with thunderous explosions that filled the skies with flames and huge clouds of smoke.

The massive Republican Palace complex along the winding Tigris River apparently took the brunt of the attack.

Heavy bombing also shook the northern cities of Mosul and Kirkuk. At least 20 major blasts were heard in the Kirkuk area alone.

U.S. officials said one of the weapons being used was a new 2,000-pound bomb designed to limit collateral damage for optimal use in an urban environment.

Air Force Gen. Richard Myers, chairman of the Joint Chiefs of Staff, said coalition warplanes had flown more than 1,000 sorties and "dropped scores of precision-guided munitions" on Iraqi military targets so far.

Iraqi Information Minister Muhammad Saeed al-Sahaf said Friday night's airstrikes had seriously damaged Baghdad's "Peace Palace" and called the U.S.-led coalition arrayed against Iraq "mercenaries."

The Peace Palace is used for visiting dignitaries. Al-Sahaf said the "Flowers Palace" -- a museum that once was a palace for the king during the days of royal rule -- also was hit.

'A huge wave of steel'
Meanwhile, coalition forces continued to make gains on the ground. Meyers said coalition troops already had traveled 100 miles inside Iraq from Kuwait.

One caravan of Bradley fighting vehicles and M1A1 Abrams and other vehicles was heading unimpeded toward Baghdad in what CNN Correspondent Walter Rodgers described as "a huge wave of steel" that stretched for 20 miles.

Rodgers, who is accompanying the 3rd Squadron of the 7th U.S. Cavalry Regiment, lead element of the 3rd Infantry Division, said the U.S. forces could reach Baghdad in two to four days.

U.S. Navy SEALs and coalition special forces troops seized two major gas and oil terminals in the northern Persian Gulf, Myers said.

The 1st Marine Expeditionary Force and coalition troops secured the port city of Umm Qasr in the Faw Peninsula and the main oil manifolds along the waterways there. Myers said Iraq's southern oil fields should be secured sometime Friday.

Marines en route to the oil fields near Basra passed homes and office buildings displaying white flags and returned the friendly waves of villagers, according to a CNN reporter traveling with them.

Iraqi state television broadcast pictures of what it says is President Saddam Hussein meeting Friday with his son Qusay.
One U.S. Marine was killed during the oil field operation, becoming the first coalition combat fatality of the war, Marine officials said. The Marine was based at Camp Pendleton, California. A second Marine was killed during the fight for Umm Qasr.

Troops of the U.S. Army's 101st Airborne Division followed other allied forces into Iraq, entering from Kuwait to little resistance Friday.

U.S. and British troops also seized two strategically important airfields in western Iraq during lightning raids, a senior U.S. military official said.

The two airfields, known as H-2 and H-3, are considered important to the continued military operation inside Iraq. U.S. intelligence suspects the H-3 field may be a weapons of mass destruction site, according to an informed official.
