It is quite probable I am over-estimating the tonnage for radar on the refits; but I haven't any good information to go on for the weights (or mass) of Dutch radars and associated equipment. I figure that it may also take into account space/weight for generator sets, CIC, and things of that sort.

CHRONOLOGICAL LISTING
Key:
- The 'Type' indicates the set's listing according to the radar chronology. Lower numbers were acquired earlier.
- The M-number indicates the year the set was acquired.
- The name is a convenient descriptor to call it by. Search sets are named after Peruvian rivers. Fire-control sets are named after Peruvian mountains.
Obviously, these names would be Peruvian names only. I "fleshed them out" with names and designations in order to keep things straight when talking about those varied applications...
Type 1 M34 Ucayali: Metric search set. Designation applied to the Bharati-provided radar used briefly during the Peruvian Civil War. Also used aboard Almirante Grau as originally commissioned.
Type 2 M44 Marañón: Metric search set. Unknown origin. Set used aboard the Libertad-class destroyers in 1943-1944. 10t total weight (3t antenna).
Type 3 M45 Putumayo: Centimetric air-search set. Dutch origin? Set used aboard the Montero-class destroyers upon completion in 1945. Total system weight:
- 5 tons on destroyers (using 1t A antenna)
- 8 tons on cruisers and larger (using 4t B antenna).
Type 4 M45 Yavarí: Centimetric surface-search set. Dutch origin? Set used aboard the Montero-class destroyers upon completion in 1945. Total system weight:
- 5 tons on destroyers (using 1t A antenna)
- 8 tons on cruisers and larger (using 4t B antenna).
Type 5 M45 Huallaga: Navigational / basic surface search set. Dutch origin? Set used aboard the Montero-class destroyers upon completion in 1945. Total system weight: 3 tons regardless of application (350kg antenna)
Type 6 M48 A/B/C Huascarán: Fire-control set of (Dutch?) origin intended for guns of 150mm up to 305mm size. Used on refits for Callao, Almirante Grau, Almirante Villar, Ancash-class and Cajamarca-class. Total system weight:
- 10 tons on ships of 7k - 11k tons (using the 2-ton A antenna)
- 12 tons on ships of 11k - 20k tons (using the 4-ton B antenna)
- 14 tons on ships of 20k tons or more (using the 6-ton C 'Grande' antenna)
Type 7 M48 Yerupajá: Fire-control set of (Dutch?) origin intended for dual-purpose guns of between 100mm and 130mm. Used as primary fire-control on destroyers with dual-purpose guns from 1948 onward, and for secondary batteries on ships of cruiser size and larger. Total system weight:
- 5 tons on destroyers as main battery FC
- 5 tons on cruisers and capital ships as secondary battery FC
Type 8 M48 Urubamba: Heavy-duty surface and low-altitude air search set of (Dutch?) origin. Total system weight:
- 12 tons on ships of 7k - 11k tons (using the 4-ton A antenna)
- 13.5 tons on ships of 11k - 20k tons (using the 6-ton B antenna)
- 15 tons on ships of 20k tons or more (using the 8-ton C 'Grande' antenna)
Type 9 M48 Mantaro: Air search set of (Dutch?) origin. Total system weight:
- 10 tons on ships of 7k - 11k tons (using the 4-ton A antenna)
- 12.5 tons on ships of 11k - 20k tons (using the 6-ton B antenna)
- 15 tons on ships of 20k tons or more (using the 8-ton C 'Grande' antenna)

- SAGEM DRBV-11 Moselle PA search radar (1 radar, 15 tons)

Brock's note: Cactus and Moselle radars have some overlap in capabilities: they are both air- and surface-search radars. However, Moselle PA's design makes it useful for very fast, broad sweeps of air and surface, tracking a lot of targets and weeding out the clutter; while Cactus/5 is a monopulse radar that can track select targets with much higher accuracy.
