Ryan Routh attempted to stab himself in the neck with a pen immediately after being found guilty of trying to assassinate President Trump, according to NBC News on September 23rd, 2025. The incident occurred as the guilty verdict was being read. This development follows a series of successful test flights of the Trident II D5 Life Extension (D5LE) Submarine-Launched Ballistic Missile (SLBM) conducted by the U.S. Navy between September 17 and September 21, 2025. One of these launches on Sunday evening was visible from Puerto Rico, illuminating the night sky, as confirmed by the U.S. Navy. These tests represent the 197th successful flight test of the Trident II D5 Strategic Weapon System. Separately, footage captured from Puerto Rico reportedly showed a nuclear submarine, likely from the U.S. or Royal UK Navy, test-firing a UGM-133 Trident II D5 Submarine-Launched Ballistic Missile in the North Atlantic on September 21, 2025. This launch was reported to potentially carry a hypersonic glide vehicle or an unusual payload, though neither the U.S. Navy nor the Royal Navy have issued official statements regarding this specific event. The U.S. and UK are the only nations equipped with the Trident II D5 SLBM. The U.S. Navy stated that a 2017 life-extension upgrade is expected to maintain the system's service life into the 2040s.
