Iran tests 5 new missiles in its "Great Prophet 5" plan. These missiles are intended for coast-to-sea, sea-to-sea. Testing these missiles is extremely important for Iran. Although there were U.S. Navy ships in this region. Also this exercise fell on the date of the 31st anniversary of the elite force. They were mainly created for testing new types of weapon systems.
Iran testing new missiles is globally important because it demonstrates to the world have Iran is constantly creating new missiles. Also that they might be doing something shady because of the date that this exercise fell on. These testings should also worry multiple surrounding countries because the types tested were not long-range. Also I believe this is important because any type of missile testing by Iran is unpredictable.
