Thyssen Submarine Family

[Voltzz]

NAVAL FORCES 1985 had a special supplement about Thyssen Nordseewerke including this depiction of the 'Thyssen Submarine Family' (image source)
Of the submarines shown, only MSV 130 and TR 1000 are unbuilt projects. The supplement has articles on both of these, but i can only find it for sale in the US and the preview from the seller only includes information on the TR 1000.
Comparative naval architecture of modern foreign submarines includes some data on both MSV 130 and TR 1000 (i attached the relevant parts of the table)
Beyond that, the only information on the MSV 130 i can find online is this short note from 1990 on a possible sale to Bahrain, published in documents of the German foreign office:

Division 424 noted on 16 January 1990: "With reference to a positive decision by the BSR (Federal Security Council) in February 1988 on the delivery of 2 small submarines of the type MSV 130 to Bahrain, Thyssen Rheinstahl Technik is now submitting a preliminary enquiry for the delivery of small submarines of the (larger) type TR 300 due to the changed wishes of its customers." As the Federal Security Council had given a positive decision on the delivery of submarines to Israel, the Foreign Office was similarly in favour of approving the "export of small submarines to Bahrain". On 20 February 1990, Legation Councillor Vorwerk made a handwritten note to this effect: "Decision BSR: positive." Cf. B 70 (Ref. 424), vol. 168252.

This note has no further information on the MSV 130, but introduces another previously unknown to me Thyssen submarine design, the TR 300.
A little more information can be found online on that submarine:

Thyssen Nordseewerke GmbH of Germany has designed a new submarine capable of extended underwater endurance using a closedcycle diesel engine.
The 98.4-foot-long by 18.7-footbeam mini-sub, dubbed the TR-300, would displace 300 tons submerged and carry a crew of eight sailors.The dimensions give a 5:1 length-tobeam ratio which is traditional in modern German submarines.
The design would use a closedcycle diesel running on oxygen drawn from a cryogenic tank. Thyssen is known to have signed an agreement with Cosworth Deep Sea Systems of Britain to use its patented gas management system.
The Cosworth system eliminates exhaust compressors which in the past limited the depth a submarine could operate with a closed-cycle diesel. The TR-300 would have only a 45-nautical-mile (nm) range when running submerged on batteries, but a 2,000-nm submerged range when running on closed-cycle diesel.

The German submarine builder Thyssen Nordseewerke has designed the TR 300, a 35m submarine employing the TNSW/CDSS closed cycle diesel propulsion system to give air-independent (AIP) submerged cruising range of 1,350m. This is a compact 450t boat for coastal and shallow water operation, particularly optimised for warm waters. The AIP system will allow mast exposure to be minimised. A profile drawing of the submarine is given.

The TR 300 seems to be from the early 90s which would explain why it is not shown in the family depiction.
Also missing from the 'Submarine Family' is the MSV 75, described by H I Sutton here. That could imply thats the MSV 130 was not just a larger variant of it, but replaced the MSV 75 in the Thyssen lineup.

In an article from Miltech 1994/4 there are pictures supposed to be showing TR300 and TR1000.
Unfortunately at least the TR300 is mislabeled. The picture actually shows a Norwegian Ula-class submarine, more specifically the S-304 HNoMS Uthaug.
Im also not entirely sure about the picture supposedly showing a TR1000. When compared with the silhouettes in my post above, the pictured model does not look like the TR1000. It is possible that the pictures were switched, and the model is instead of a TR 300. Labeling the Ula as a TR1000 makes more sense as there seems to have been some relation between these two submarine designs.

Some more stuff on the Cosworth Closed Cycle Diesel AIP mentioned above for the TR-300

Covert mini-sub announced
HDW and Thyssen Nordseewerke have developed a design for a 300-ton coastal submarine, the Type TR300, which is driven exclusively by a closed-cycle diesel engine (which is also capable of open cycle operation). The TR300 is designed for three primary missions: attacks on surface targets, covert operations, and offensive and defensive minelaying operations. Special efforts have been made to minimize the size and signature of the TR300 which is theoretically capable of operating in water depths of only 10m.
The TR300 is 30m in length with a pressure hull diameter of 4m and breadth overall of 5.7m. TR300 is 6.2m high with a displacement of 300m^3 and a reserve buoyancy (relative to surface displacement) of 10 per cent. The boat would have a complement of eight and endurance of 14 days. Maximum operating depth is 100m, maximum submerged speed 13kt (both on open and closed cycle). Submerged cruising range on batteries if 45nmi. For closed cycle air-independent operation submerged cruising range is 2,000nmi.
