Significance

The aircraft reached Poland in 2006–2008 and, as the minister said, need upgrading after twenty years given current threats. According to the defence minister, all upgrades will be carried out at Polish defence plants in Bydgoszcz, which gives work to WZL-2 and the PGZ group. The F-16 purchase and base infrastructure have their own records.
