Nuclear USS Iowa sub calls to mind Ames’ role in the Manhattan Project | Opinion
Iowa State quietly saved the Manhattan Project, assured an Allied victory and forever changed history.
Watching the young men and women sailors scramble aboard the new USS Iowa submarine as ship sponsor Christie Vilsack announced, “Board our boat and bring her to life!” I wondered if they understood Iowa State University’s role in ushering in the nuclear age?
Did these sailors know Iowa State was the only university to receive the Army Navy “E for Excellence” banner after World War II?
At that moment I reminded myself to send the book, “Wilhelm’s Way — The Inspiring Story of the Iowa Chemist Who Saved the Manhattan Project” to the submarine commander of the nuclear-powered USS Iowa. I wanted him to know how an ISU chemistry professor changed world history.
To understand the story, you need to return to the end of 1941.
Theoretically, the idea of nuclear energy and a possible nuclear bomb had been conceived by physicists. However, to test the theory, thousands of pounds of pure uranium were needed to create the first nuclear bomb. Chemists at Westinghouse and prestigious universities had only created mere grams of not-quite-pure uranium. The newly established Manhattan Project was stalled, unless someone figured out how to purify uranium — and fast.
By February 1942, Iowa State’s head of physical chemistry, Frank Spedding, was contacted by the University of Chicago’s Manhattan Project team. He learned of the project’s numerous challenges, including the need for a process to purify uranium which required a special furnace. Fortunately, Iowa State had such a furnace and Spedding immediately brought in ISU professor Harley Wilhelm, a sharecropper’s son from southern Iowa, who understood chemistry and metallurgy. Though completely under-resourced in a ramshackle lab, Wilhelm began experiments to purify uranium.
Scientific innovation is not always pretty. Explosions and fires seemed routine in the Physical Chemistry lab that summer. But Wilhelm and a team of graduate students kept trying new approaches to purify uranium and learn from their failures.
By August 1942, the first glimmers of success appeared. A 20-gram piece of pure uranium was produced in the lab! The basic process worked. But could the process be made more efficient and larger?
By Sept. 23, Harley Wilhelm and team had done it. He boarded the night train to Chicago, carrying an 11-pound ingot of pure uranium to show the Manhattan Project leaders. Upon seeing this much pure uranium, the director’s “eyes bugged out and his jaw dropped,” according to Wilhelm. Could an Iowa State chemistry professor have accomplished what the best funded private and university labs in the nation had failed to achieve?
To test the claim, they asked Wilhelm to saw it in half to prove it did not have a cavity inside. The sawing resulted in a small fire but showed a pure solid mass of uranium. They sent a portion to MIT to confirm its purity. It was pure.
By November, the War Department signed a contract with Iowa State to produce pure uranium through Operation Quik Phix. In the next few years, the Ames facility, called “Little Ankeny,” delivered 2 million pounds of pure uranium to the war effort. Moreover, the Ames Process yielded pure uranium at a cost of $1.55 per pound, instead of the $1,000 per pound anticipated by Westinghouse, saving the government hundreds of millions.
With the War Department’s gratitude, Iowa State and Wilhelm both received the Army Navy “E for Excellence” banner. Iowa State had quietly saved the Manhattan Project, assured an Allied victory and forever changed history.
On the submarine pier, I listened with pride as Gov. Kim Reynolds and U.S. Rep. Mariannette Miller-Meeks recalled the previous versions of the mighty USS Iowa. When Christie Vilsack charged the crew to “bring her to life!” I knew the living heart of this nuclear-powered submarine beat with the pure-uranium-powered energy and science of Iowa State University and its brilliant professor, Harley Wilhelm. His story constantly reminds me of the importance of university researchers and their impact in times of war and peace.

How much rain does Des Moines get? See the 5 wettest days on record
Wondering how the rainfall total compares? Here are the five wettest days on record for Des Moines, Iowa.
Drought conditions in Iowa improved for a second consecutive week, though areas of moderate drought expanded in parts of the state.
The U.S. Drought Monitor offers a state-by-state tracking of drought conditions nationwide. New maps and forecasts are released each Thursday. What are the current drought conditions in Iowa?
U.S. Drought Monitor map: How much of Iowa is in a drought?
The latest Drought Monitor report, released on Thursday, June 18, showed about 46% of Iowa experiencing some form of drought. This continues the streak of conditions improving week to week in Iowa. The previous report, released on June 11, showed that 63% of the state was experiencing some form of drought.
The most recent report reflects conditions as of 8 a.m. June 16, right as storms were sweeping through Iowa, with parts of eastern Iowa seeing more than 2 inches of rainfall. Light rainfall on June 17 led to areas like Iowa City and Burlington reporting around an inch of rain.
Here is the breakdown of current drought conditions in Iowa:
- 61% of the state of Iowa is experiencing no drought conditions
- 39% of Iowa is experiencing abnormally dry conditions
- 7% of Iowa is experiencing moderate drought conditions
- 0% of Iowa is experiencing severe drought conditions
Even though drought conditions have improved overall in Iowa, the area experiencing moderate drought increased from the week of June 11, particularly in northern Iowa. Much of Cerro Gordo, Hancock and Kossuth counties are under D1 conditions, with nearby Palo Alto, Winnebago, Floyd and Mitchell also in moderate drought.
Pockets of moderate drought also persist along the northwest edge of Iowa in Lyon, Sioux and Plymouth counties. In eastern Iowa, Jackson, Clinton and Scott counties saw their moderate drought status ease week to week.
Most of the U.S. is facing drought conditions
About 73% of the U.S. is experiencing some level of drought, a 2-percentage-point improvement from the prior week. Some of the most intense drought conditions are in the southeast and the mountain west.
Iowa Drought Monitor tracks conditions weekly
The U.S. Drought Monitor offers a state-by-state tracking of drought conditions nationwide. New maps and forecasts are released each Thursday.
The intensity levels range from abnormally dry, or D0, to exceptional drought, or D4.
Typically with D0 conditions, corn can show drought stress. Pond levels start to decline under moderate drought conditions and soybeans abort pods, according to the Drought Monitor. The Drought Monitor also has a look-back chart that compares drought conditions from 3 months ago up to 1 year ago.

Confirmed tornadoes were reported in Illinois and Iowa Wednesday night as severe weather descended on a large swath of the Midwest.
According to the National Weather Service, a confirmed tornado was reported near the small northeast Iowa community of Harpers Ferry at 5:10 p.m., while a second confirmed tornado rolled through Charleston in central Illinois at about 6:40 p.m. local time.
Both tornadoes were flagged by the weather service as a “particularly dangerous situation,” a rare designation used by the weather service for environments in which “strong and violent tornadoes” are possible.
Photos and videos obtained by CBS News showed extensive damage in Charleston, with downed trees and power lines. Hail that measured 2.75 inches was also reported in the Charleston area, according to the weather service.
“There are a large number of trees blocking roadways throughout Charleston at this time,” Charleston police said in a Facebook post. “Unless it is an absolute emergency, do not drive or attempt to go anywhere.”
The city of Charleston later declared a local state of emergency.
One cell phone video captured the terrifying moments what appeared to be a large tornado tore through Effingham, Illinois, located about 40 miles southwest of Charleston.
Larry Thies, coordinator for the Effingham Emergency Management Agency, told CBS News that initial information indicated damaged buildings, trailers, and downed power lines and trees. He said officials were working to set up an emergency operations center, but were facing challenges because internet was down in the area.
The extent of the damage to region was still unclear. There was no immediate word of injuries or fatalities. CBS News senior meteorologist Rob Marciano said there were at least seven reported tornadoes during the weather event.
According to utility tracker PowerOutage.us, at least 55,000 customers were without power in Illinois.
Earlier Wednesday, Marciano reported that more than 125 million Americans were facing severe weather advisories, including the Gulf Coast states, which were under flood alerts due to Tropical Storm Arthur. Speaking on “CBS Evening News,” Marciano said such ripe tornado conditions were rare for June.
“This is unique for June, this is unusual to have such a strong jet stream just screaming across the country, then you’ve got the summertime tropical moisture coming in…and then some cold air coming in,” Marciano said. “And winds coming at different direction, at different levels, creating that spin. So what that equates to is really the high probability of seeing, not just tornadoes, but intense tornadoes of EF2 strength or higher on the ground for a long time. And also damaging winds at 75 mph or higher, and of course big time hail.”
