Could NATO tolerate Soviet-built Icelandic frigates?

What would happen if Iceland tried to buy Soviet ice-capable frigates?

NATO might tolerate the purchase unless allies were willing to subsidize a suitable Western alternative that Iceland could afford.

The hypothetical purchase would create political discomfort but not necessarily an alliance-breaking crisis. Iceland could argue that it needed an ice-capable frigate and could not afford a bespoke Western design. The United States and other allies would then choose between subsidizing a suitable alternative and tolerating the Soviet-built ship. Greece's operation of Zubr hovercraft shows that alliance membership has not always produced complete equipment standardization.
