Sokol Altius. The Sokol Altius (also Altair) is a medium-altitude long-endurance Russian unmanned combat aerial vehicle developed by OKB Sokol (formerly known as Simonov Design Bureau) and Tranzas to perform reconnaissance, strike and electronic attack missions on behalf of the Russian Aerospace Forces and Navy. The program started in 2011 and thus far 3 prototypes have been built.

The Altius is comparable to the striking and reconnaissance capabilities of the US-made MQ-9 Reaper and RQ-4 Global Hawk UAVs.

Development
The Altius program started in October 2011 after the Russian Ministry of Defence awarded a 3 billion Ruble contract with OKB Sokol (Kazan) and resulted in three demonstrators. The first one, called Altair, was unveiled in 2014 and flew for the first time in 2016, while the second demonstrator, the Altius-M, was spotted for the first time in 2017. 
At the end of 2018, the Ministry of Defence transferred project to the Ural Civil Aviation Plant (Yekaterinburg). The third demonstrator, the Altius-U, made its maiden flight in 2019. The fourth variant, the Altius-RU, is considered the final evolution of the project for serial production. The drone entered service in 2021.

The development of the Altius had known several technical delays because of practical setbacks and cost increases, such as losing the right to use French engines, forcing Russia to develop their own engines for the drone. Altius was originally planned to be fully operational by 2018. In April 2018, the authorities arrested the Director General of OKB Sokol, Simonov Alexander Gomzin, whom the investigation suspected of embezzlement of 900 million rubles allocated for the development of the Altius drone.

The Altius will be the backbone of the fleet of Russian heavy drones, the Izvestia daily reported in September 2019.

On 21 February 2021, it was reported that a state contract had been signed between the manufacturer and the Russian MoD for the supply of the first batch of Altius, with delivery expected in 2021.

Design
Altius is built according to the classical aerodynamic design with a highly located wing of a large scope and a V-tail. It is known that Altius was built with the wide use of composite structural materials. Altius uses two new VK-800C turboprop engines developed at the Klimov Design Bureau.

Chinese destroyer Hefei (174). Hefei (174) is a Type 052D destroyer of the People's Liberation Army Navy. She was commissioned on 12 December 2015.

Development and design 
The basic ship type and layout of the Type 052D guided-missile destroyer is the same as that of the Type 052C destroyer, but compared to the earlier Type 052C destroyer, the Type 052D superstructure has a larger inclination angle and provides better stealth performance. At the same time, the 052C helicopter hangar is located The left side of the hull axis was changed to the center axis of the ship on Type 052D; a pair of small boat storage compartments were added on both sides of the hangar, similar to the design on the Type 054A frigate.

The close in weapon system is composed of a H/PJ-12 short-range defense weapon system located in front of the bridge and a 24 Hongqi-10 air defense missile system located on the top of the hangar, which is combined to form a ladder interception. The original 100mm naval gun was replaced by a higher height and better stealth model H/PJ45 naval gun. On May 13, 2019, the extended version of the 052DL was exposed. The hull of the 052DL is basically the same as the 052D, but the helicopter deck is lengthened to prepare for the Zhi-20 to board the ship.

The Type 52D is the first Chinese surface combatant to use canister-based universal VLS, as opposed to the concentric type VLS carried aboard earlier vessels. 64 cells are carried; 32 forward and 32 aft. The VLS is reportedly an implementation of the GJB 5860-2006 standard. The VLS may fire the extended-range variant of the HHQ-9 surface-to-air missile, YJ-18 anti-ship cruise missiles, and CY-5 anti-submarine missiles.

Construction and career 
Hefei was the third ship of the class and launched on 1 July 2013 at the Jiangnan Shipyard in Shanghai. Commissioned on 12 December 2015.

Hefei and few other PLA Navy ships conducted an exercise about 360 km south of Yonakunijima and was spotted by JS Akizuki on  25 May 2016.

8 February 2018, Hefei transits the South China Sea. She was surveilling the USS Carl Vinson's task force operating nearby.

On 25 May 2016, Honghu, Lanzhou and Hefei were seen conducting a replenishment exercise in the Sea of Japan.

On 26 August 2024, Hefei arrived at the Port of Colombo, Sri Lanka, for a formal visit, accompanied by Wuzhi Shan and Qilian Shan. After completing the official engagement, the three vessels are scheduled to depart the island on 29 August 2024 and conduct a passing exercise with a Sri Lankan naval vessel off the coast of Colombo.

Type-X (unmanned ground vehicle). The Type-X is a robotic combat vehicle designed and built by Milrem Robotics. Unveiled in 2020, it is the second UGV to be manufactured by the company after its flagship product THeMIS.

Design and purpose 

The vehicle is operated from a safe distance by a combination of augmented artificial intelligence (AI) and a remote system operator which means it considerably raises troop survivability and lowers lethality risks by increasing standoff distance from enemy units. It features a tracked design with armor protection which increases its cross-country performance and durability. 

The Type-X is designed to be highly modifiable and easily upgradable, meaning it can be fitted with either autocannon turrets up to 50mm, such as  John Cockerill CPWS II or various other weapons systems, such as ATGMs, SAMs, radars, mortars etc. The heavy armament that can be mounted on the vehicle means that the Type-X provides equal or overmatching firepower and tactical usage compared to traditional infantry fighting vehicles.

In October 2020, Milrem and the Israeli company UVision announced that they are co-developing a variant of the Type-X and THeMIS that can mount a multi-canister launcher for the latter's Hero-120 and Hero-400EC loitering munitions.

The intended main purpose of the Type-X is to bolster and support the combat capability of mechanized units, for example providing convoy and perimeter or base defence. It can drive along in a convoy autonomously using the "follow-me" technology, giving the formation additional eyes and firepower. The system can also be utilized to localize and engage lower range targets and provide flanking support.

The Type-X is designed to deploy at a weight below the 12-ton mark for rapid deployment into the combat theater, either by parachute or by heavy lift helicopter, providing vital fire support to airborne troops while maintaining a logistic footprint compatible with the logistics of a parachute-deployed force. The C-130J and the KC-390 can carry one Type-X vehicle, an A400M two and a C-17 5-6 vehicles.

Atlantic City catboat. The Atlantic City catboat is an American sailboat that was designed by D. Martin as a cruiser and first built in 1980.

The design can be confused with the unrelated 1913 Atlantic City Catboat Class.

Production
The design was built by Mark-O Custom Boats in the United States, starting in 1980, but it is now out of production.

Design
The Atlantic City is a recreational sailboat, built predominantly of solid laminate fabmat (stitched fiberglass fabric), with wood trim. It is a gaff rigged catboat with aluminum spars. The hull has a plumb stem, an angled transom, a shallow-draft, transom-hung rudder controlled by a tiller or optional wheel and a retractable weighted centerboard. It displaces  and carries  of ballast.

The boat has a draft of  with the centerboard extended and  with it retracted.

The boat is fitted with a German BMW diesel engine of  for docking and maneuvering. The fresh water tank has a capacity of .

The design has sleeping accommodation for six people, consisting of a convertible aft dinette area double berth and two forward cabin settees with pilot berths above them. It has an optional galley on the port side just forward of the companionway ladder. The galley is L-shaped and is equipped with a two-burner stove. A navigation station and a fireplace were also factory options. The head is located in the forepeak. The cabin has  of headroom.

For sailing the design is equipped with mainsail hoops in place of more conventional cars.

Operational history
In a 1994 review Richard Sherwood described the design as a classic catboat.

In a 2010 review Steve Henkel wrote, "if you've ever heard the sailor's description of a cozy cruiser, 'drinks six, eats four, sleeps two,' you'll appreciate that this boat is different: she drinks eight (if squeezed into the cockpit at anchor), eats four (at a dinette below, unless you go for trays on laps), and sleeps six (double berth under the  starboard cockpit, upper and lower berths to starboard forward, and a dinette that converts to another double). We can’t imagine who would want to sleep six in what amounts to a large walk-in closet, unless it’s a family with four small kids. Best features: For the large, close-knit family that is totally committed to catboats, this might be a good choice ... Worst features: Her sail area of 452 square feet, all in one big piece of cloth, can be hard to manage. Her centerboard shape, with its cutout forward to avoid cluttering up the cabin with a centerboard trunk, could be a problem too."

Allan Griffiths Watson. Allan Griffiths Watson (1876–1945) was South African Railways (SAR) Chief Mechanical Engineer (1929-1936).

Watson was born in 1876 in Hopetown, Cape Colony. He received his early education in Cape Colony. He moved to Scotland in 1895 to work for Neilson, Reid and Company at their Hyde Park Works; returning five years later to work for the Cape Government Railways. He rose up through various positions in the CGR and its successor, the South African Railways and Harbours Administration, until he was appointed to succeed Lieut-Col. F. R. Collins as Chief Mechanical Engineer as of 1 April 1929.

Soon after Watson was appointment as Chief Mechanical Engineer, he set out on a program of standardisation of locomotive boilers and engine parts, which ultimately led to a considerable reduction in the time taken for locomotive repairs. At the time, 88 different types of locomotive were in service on the South African Railways, for which some fifty types of replacement boiler were still being ordered prior to 1929.

He was responsible for many innovations and improvements to SAR locomotives. He raised the boiler pitch from  to  in one swoop, whereas it had been increased from  to  by increments of  or so at a time during the previous thirty years. He introduced his own design of flexible side and roof firebox stays with rocking washers, which proved to be resistant to the build-up of scale which gradually rendered conventional types of stay rigid and inflexible.

He retired in 1936, and died in Cape Town on 13 November 1945.
