The Argentine Navy struggles to meet maintenance and training requirements because of financial problems and import restrictions. The "Espora" class has not been immune – "Espora" herself spent 73 days in South Africa in late 2012 in a dispute about payment for repairs to its generators. The operational status of "Parker" and "Rosales" is not clear, as of November 2012 they were waiting for spares, whilst "Spiro" lost her sonar in a grounding accident in August 2012. In 2019, Rosales was reported as scheduled to be scrapped. However, one year later training activities were still being conducted on her.
