The annual Waterstone Bank Air and Water Show kicks off Saturday, and will include an appearance by a KC-46A Pegasus -- a next generation tanker that's officials hope to bring to the 128th Air Refueling Wing at Mitchell International Airport.

Leaders of the 128th hope the appearance of the KC-46A will boost enthusiasm for the mission of the air refueling wing, and highlight a move to upgrade the aircraft the facility uses.

Here's what's to know about the appearance of this huge aircraft at the show.

What is the 128th Air Refueling Wing?

128th Air Refueling Wing is part of the Wisconsin Air National Guard Base located at General Mitchell International Airport. The wing participates in national and international missions, and provides critical aerial refueling services for the Air Force, Navy and Marine Corps.

Since 1977, the operations have been conducted using the KC-135 Stratotanker.

What do tanker planes do?

These planes allow fighter jet pilots to refuel their aircraft mid-flight, saving time and optimizing distance covered.

What's wrong with the old model?

Officials say the 10 KC-135 tankers at the base are outdated and lack the capabilities available on the newer aircraft. The Stratotankers were built between 1955 to 1965.

"The biggest risk to aging aircraft is metal fatigue and corrosion," said Col. Charles Merkel, commander of the 128th. "We do a great job managing that and the airplanes are very safe to fly, but age is always a concern."

What features does the KC-46 offer?

The KC-46A Pegasus, or KC-46 for short, offers increased cargo and fuel capacity. The tanker can store 212,000 pounds of fuel and 65,000 pounds of cargo. It can hold up to 58 passengers, and the plane's tough exterior allows it to weather even the most difficult conditions.

"The KC-46 brings better integrated avionics, increased situational awareness, built-in self-protection systems, and increased cargo capacity," Merkel said.

How would the addition of the KC-46 boost the community?

The annual economic impact of 128th on the community totals $83 million and the base employs about 1,650 people. Attaining the KC-46 would cement the base's flying mission in Milwaukee for years to come, Merkel said.

Securing the tanker will also boost the economy in the short-term, he said. If the KC-46 is obtained, the base will need updating to host the tanker, such as a larger aircraft ramp and new hangers. That new construction would provide an estimated $250 million impact to local construction workers, the 128th says.

There are currently 15 other military bases vying for the new model, and the 128th will learn later this year if it places within the top 5 candidates.

"I'm confident that the base will continue on in the future if we don't get selected, but we don't want to pass up on the opportunity," Merkel said.

When will the KC-46 fly during the Air and Water Show?

The tanker will fly between 2:45 and 3:00 p.m. on Saturday and Sunday. By exhibiting the KC-46 during the airshow, Merkel hopes to build awareness and increase local support.

"It's such a great opportunity to get out there and show the public what we do."
