Note:
(a) Taiwan received “submarine-launched Harpoon Block II anti-ship cruise missiles * * * The delivery included 32 UGM-84L encapsulated all-up rounds, two UTM-84L exercise missiles and two UTM-84XD certification and training rounds.”
(i) Harpoon (missile)
en.wikipedia.org/wiki/Harpoon_(missile)
(Boeing; "The missile's launch platforms include [A] Fixed-wing aircraft (the AGM-84, without the solid-fuel rocket booster) * * * [C] Submarines (the UGM-84, fitted with a solid-fuel rocket booster and encapsulated in a container to enable submerged launch through a torpedo tube);" section 1.4 Harpoon Block II: "Harpoon Block 2 missiles are designated AGM/RGM/UGM-84L [citation needed]")

The last statement is wrong. See (c) below.
(ii) “all-up round” (AUR)
(A) This is the best, and only, definition in the Web:
The British Strategic Systems Programs [SSP]. US Navy, undated (under the heading: Facts; Polaris-Poseidon-Trident)
www.ssp.navy.mil/about/history_facts_6.shtml
("The TOMAHAWK missile, while onboard the SSGN [guided missile submarine], is encapsulated within the legacy Capsule Launching System (CLS). The CLS provides environmental protection, missile ejection using a gas generator, and an umbilical cable for communication with the shipboard components. This configuration is referred to as the TOMAHAWK All-Up- Round (AUR)")

AUR seems to be always American-made submarine-launched missiles.
(B) All-up-Round 整装弹. nciku [Beijing] Dictionary, undated.

(iii) The “T” in “UTM” stands for “training.”

(b) “Fu MEI, director of the Taiwan Security Analysis Center”

(c) “The ‘L’ designation on the UGM-84L indicates it has a littoral suppression capability that allows limited coastal target attack, such as upon ships inside a harbor, harbor infrastructure, power grids, invasion staging grounds, and command-and-control centers, a Taiwan defense industry source said. ‘In this sense, the introduction of the sub Harpoon could be seen as providing Taiwan with a small measure of asymmetric counterforce capability,’ Fu Mei said”

AGM-84 Harpoon SLAM (Stand-Off Land Attack Missile). Federation of American Scientists (FAS), undated
www.fas.org/man/dod-101/sys/smart/agm-84.htm
("The Harpoon Block II is an upgrade program to improve the baseline capabilities to attack targets in congested littoral environments. The upgrade is based on the current Harpoon. Harpoon Block II will provide accurate long-range guidance for coastal, littoral and blue water ship targets by incorporating the low cost integrated Global Positioning System/Inertial Navigation System (GPS/INS) from the Joint Direct Attack Munitions (JDAM) program currently under development by Boeing. GPS antennae and software from Boeing's Standoff Land Attack Missile (SLAM) and SLAM Expanded Response (SLAM ER) will be integrated into the guidance section. The improved littoral capabilities will enable Harpoon Block II to impact a designated GPS target point")

Recall that the original Harpoon was designed for anti-ship only, in an open sea (as opposed to a target in a “congested” environment.

(d) "The missile’s nominal maximum range of 150 nautical miles would substantially expand potential targets for Taiwan’s submarines, which are limited to about 30,000 yards, or about 15 nautical miles, by their SUT torpedoes. 'That is a roughly 100-fold increase in the area that could be covered by each submarine so armed,' Fu Mei said."

For SUT torpedo, see
list of torpedoes by name
en.wikipedia.org/wiki/List_of_torpedoes_by_name
("Name: SUT, Country: Germany, In service date: 1967, Dimension: Diameter: 533 mm (21 in)")

SUT stands for "Surface and Underwater Target."

(e) "Over the past decade, Taiwan has been working to integrate a data link terminal on its two Dutch submarines so they can receive targeting data from offboard sensors and shore-based command-and-control facilities while underway."
(i) Meaning off a ship or stock exchange, "offboard" (adj) is the opposite of "onboard"
(ii) underway (adj; First Known Use 1743)
"occurring, performed, or used while traveling or in motion <underway replenishment of fuel>"

My comment: The last paragraph quoted FAS, about the firing mechanism. Since the date of publication, I have not been able to find anything better than that. In fact, I have researched for close to a decade, how a submarine-launched missile is fired. All in vain. No text, no graphic, not video, nothing. I believe it is a trade and military secrets. Otherwise China would have successfully developed JL-1 and -2 long time ago.
