Ukraine has been able to increase its fixed-wing aircraft availability over the past several weeks due to US-cordinated supply of spares and equipment to keep the aircraft in operation.
"Ukraine has received through United States coordination and provision, enough spare parts and additional equipment such that they have been able to put in operation more fixed-wing aircraft in their fleet than they had even two to three weeks ago," Pentagon Spokesperson John Kirby said Tuesday.
"As a matter of fact, through our efforts to provide them spare parts and coordinate the delivery of spare parts from other countries, they have been able to increase their fleet by quite a number," the spokesperson said.
