The base, in southwest Germany, has become one of its two runways - which are both about two miles long - into a large tent city to give living quarters for the tens of thousands of Afghans who have been left there.
Those tents - which have been photographed from the air to show the sheer scale of the evacuation operation, are split into pods to give their occupants' privacy, with hundreds of porta potties also visible along the edges of the airstrip.
Only men sleep in the tents, with women and children housed singly in hangars usually used to store military aircraft at the base, which is run jointly by the US Air Force and Army.
About a fifth of all people left by the U.S. from Kabul were taken to Ramstein, 100 miles southwest of Frankfurt. The rest went largely to Qatar and Kuwait, with some traveling via Italy and Spain.
Those evacuees then fly through Philadelphia or Washington Dulles airports for resettling in the United States - with most of those flying out unaware of where their final destination will be.
The first arrivals landed on August 20, after Qatar quickly reached capacity.
At the time, Brigadier General Joshua Olson, commander of the 86th Airlift Wing and Ramstein's installation commander, said that the base could hold 5,000 evacuees. Two weeks later, it is housing nearly three times as many: as of September 1, almost 12,000 evacuees had left the base, while another 14,900 remained.
Since August 20, about 106 planes have landed there - mostly the C-17 jets which have become synonymous with the Kabul airlift.
"We were maxed out and the flow kept coming," said Olson, speaking to CNN.
"I had to close part of the base for Afghan evacuees. Because you can't put them in the elements. It's 50 degrees Fahrenheit outside and raining. I can't put people out in that. Especially kids.
"So, that was one of the things that inflow and outflow. We were bringing them in faster than we could get them out. And that's hard."
Olson said he believes the process will be over in the next few weeks. Women and children sleep on cots inside the huge hangars of the airbase while the men sleep 40 in a tent.
