The global defense trade show circuit was expected to make a full comeback this year after a coronavirus hiatus. That is, until the fast-spreading delta variant started sowing fresh doubts on which events will take place and in what format.

Here is an overview of some of the remaining year’s biggest events, with information from organizers on what to expect. While much of the information is fluid, most are requiring masks and promising additional cleaning. Stay tuned for some form of vaccination requirements, which continues to be an uneven process for individuals traveling across the Atlantic, for example.

AFA Air, Space & Cyber, National Harbor, Md., Sept. 20-22.

In-person or virtual? This year’s big air warfare gathering is on the books as an in-person affair with a virtual option.

Masks required? The Air Force Association, the event’s organizer, says all attendees must wear masks indoors, except while eating or drinks.

Additional policies: AFA has said Air Force Secretary Frank Kendall authorized in-person attendance for Air Force and Space Force personnel, both military and civilian, if they are fully vaccinated. The association says non-government attendees must present proof of being either fully vaccinated or having tested negative within three days. “Individuals unable to present the required documentation should update their registration to a virtual-only option,” AFA adds.
