As the Dutch article says Zr.Ms. Van Speijk has been laid up for 3 years, the article implies that the crew freed up from the Rotterdam may enable Van Speijk to resume operations with manning priority shifting to frigates.
What is familiar is that the replacement of the M-Frigates (Van Speijk and Van Amstel) and the LCF-Frigates (De Zeven Provinciën class) have both been pushed back, in the case of the Ms twice and they will now be around 40 years old when they are replaced.
