"We are standing by, ready to not only backfill need as it arises with new F-16 builds but also any modifications to F-16s as well as training, equipment and systems," St. John was quoted by the Financial Times as saying ahead of the Paris Air Show, adding that a decision on this would be made only after discussions between Ukraine, the US and its NATO allies.
Lockheed Martin may also consider establishing a base in Ukraine or near its territory after conflict is over, the company official said.
Last week, NATO Secretary General Jens Stoltenberg said that the timing of the delivery of F-16 fighter jets to Ukraine would depend on progress in the training of Ukrainian pilots.
Earlier in the month, Ukrainian President Volodymyr Zelensky said at a European Political Community press conference in Chisinau that a number of countries were ready to provide Ukraine with F-16s, the fighter jet of its choice.
Russia has slammed the possible delivery of F-16s to Ukraine, warning that the jets will become a legitimate military target for Russian forces. Russian Foreign Minister Sergey Lavrov has warned that the delivery of F-16 fighters to Ukraine will be a further escalation because the jets have a modification that makes them nuclear-capable.
